Experimenting with Thermal Switches

Thermal switches (also called thermal sensors) are used in a variety of industrial, home/kitchen appliance, and HVAC products. They are typically used as protection against overheating, overcooling or overloads when used in a motor protection circuit. The most widely used thermal switches are bimetallic thermal switches and thermistors.

Bimetallic thermal switches consist of two strips of different metals that are bound together. Bimetallic thermal switches leverage the expansion of metals when they are heated. As the strip is heated, the different metals bend in different directions opening or closing a switch contact (NO/NC).

A thermistor is a type of resistor whose resistance changes with temperature changes. Thermistors are widely used as inrush current limiters, self-resetting overcurrent "fuses", and self-regulating heating elements.

The bimetallic thermal switches have been a mainstay for the design of thermostatic temperature controls and over-temperature protection over many decades. Thermistors have also been widely used, but neither type offers high accuracy or stability needed to meet the latest demands of consumers and industrial end users.

In response, thermal ferrite materials such as KEMET’s Thermorite^® have emerged to enable a new generation of thermal switches (temperature sensors) that deliver greater accuracy, faster response times, and better stability with respect to ageing and environmental conditions such as humidity.

In this design challenge, participants will be given a kit of thermal switches based on KEMET’s Thermorite^® to experiment with their use, application, response, and more.

Thermal Switch/Sensor	Thermorite^® Reed Switch	Bi-metallic Strips	Thermistors
ContactType	Mechanical	Mechanical	Electrical
Operating Principle	Switching the reed switch ON/OFF at a trigger temperature of the thermo-ferrite material	Switch ON/OFF at a trigger temperature by using two metal strips that have different thermal expansion coefficients which deform by temperature	Semiconductor (NTC) or Ceramic (PTC). Change in resistance due to temperature.

What is Thermorite?

Thermorite is temperature sensitive ferromagnetic material that has soft magnetic characteristic under curie temperature. The material’s saturated magnetic flux density decreases as material temperature goes up, and it becomes paramagnetic (ferrite lose its magnetic property) rapidly when the temperature of the material reaches at curie temperature.

What is Curie Temperature? The Curie temperature is the temperature point above which some materials undergo an abrupt change such that they lose their permanent magnetic properties. The Curie temperature is synonymous to the Curie Point. It was named after scientist Pierre Curie who discovered the laws revolving around magnetic properties changing due to temperature changes.

Depending on its composition, Thermorite can be tuned to lose its magnetic permeability quickly at a predetermined temperature and instead behave as a paramagnetic material. KEMET’s TRS and OHD series of temperature sensors exploit this property to actuate a reed switch at a specific temperature determined by the composition of the thermosensitive ferrite. The switch can be designed either to open or close at this temperature.

How Does the Thermorite^® Reed Switch Work?

The reed switch contains a pair of Fe-Ni (iron-nickel) reeds encased in a glass tube filled with inert gas. Encasing the reeds in this way ensures the switch is dust proof, explosion proof and corrosion resistant.

A Thermorite tube surrounds the reeds (Figure 1), and acts as a magnet at temperatures below the set point determined by the material composition. When the temperature rises above the set point, the Thermorite loses its magnetic properties and the magnetic field collapses allowing separated reed contacts to touch (make-type switch) or closed contacts to separate (break-type switch). The mechanism shows very little degradation due to metal fatigue. Tests under standard conditions have demonstrated switch lifetime based on metal fatigue of 500,000 on/off cycles.

Figure 1. Reed switch operating principle (Source: KEMET)

a) Break-type Switch

The break-type switch consists of the Thermorite® cylinder that surrounds the reeds. At both ends of the cylinder are ring-shaped permanent magnets, as shown in Figure 2.

Figure 2. Structure of break-type sensor (Source: KEMET)

Below the temperature set point, when the Thermorite acts as a magnetic material, the magnetic field acting on the reed is a single loop as if caused by one large surrounding magnet. This magnetic field induces opposing poles in the reeds, causing them to be attracted thus turning the switch "ON".

When the temperature set point is exceeded (i.e., curie temperature), the Thermorite loses its magnetic property. At this point the single magnetic field becomes two separate fields associated with the permanent magnets at each end of the switch, causing the contacts to separate. This turns the switch "OFF".

b) Make-type Switch

The make-type switch has a similar structure to the break-type, except for an additional spacer inserted in the middle of the Thermorite cylinder as shown in Figure 3.

Figure 3. Make-type switch structure(Source: KEMET)

When the surrounding temperature is lower than the temperature set point, the spacer causes the separated pairs of permanent magnet and Thermorite® to create two independent magnetic fields that act in a similar way to those of the break-type sensor in high-temperature mode. The contacts are separated and the switch is turned “OFF”.

When the temperature around the make-type switch rises above the set point, the Thermorite components lose their magnetism. The independent fields due to the permanent magnets closer to the ends of the reeds cause the contacts to join thus turning the switch “ON.” Table 2 summarises the switch states at temperatures above and below the set point defined by Thermorite composition.

Switch Type	Status below temperature set point (Thermorite is magnetic)	Status above temperature set point (Thermorite is non-magnetic)
Make	OFF. Contacts open	ON. Contacts closed
Break	ON. Contacts closed.	OFF. Contacts open

But how you experiment with them depends are your interests and what stirs your curiosity about this relatively new product and how it functions.

What do I need to do to win the Grand Prize or Runner Up Prize?

After the month long enrollment period is completed, and the 15 FREE thermal switch component kits are shipped, you will have 8 weeks to complete your experiments, write two blogs, and share what you learned about Thermorite® Reed Switches. You will be judged by the quality of your final blog and what you learned about these components.

Can I still be elgibile for the Grand Prize or Runner Up Prizes if I am not selected for one of the 15 FREE kits?

Yes, on the condition that you obtain the Thermorite® Reed Switches featured in the kit and perform experiments with those components, and post your blogs in the Experimenting with Thermal Switches Group. You must write and post two blogs. Also, please notify rscasny@newark.com with links to your two blogs.

What do I get if I don't win the Grand Prize, but I wrote the two blogs?

If you write two blogs and post them in the Experimenting with Thermal Switches Group by the deadline on March 28, 2022, you have successfully completed your entry in the competition. If our judges do not select you for the Grand or Runner-Up prizes, you will be eligible to receive the finisher prize. But remember, you have to write two blogs by the deadline to be considered a finisher!

Experimenting with Thermal Switches

In this design challenge, participants will be given a kit of thermal switches based on KEMET’s Thermorite^® to experiment with their use, application, response, and more.

Thermal Switch/Sensor	Thermorite^® Reed Switch	Bi-metallic Strips	Thermistors
ContactType	Mechanical	Mechanical	Electrical
Operating Principle	Switching the reed switch ON/OFF at a trigger temperature of the thermo-ferrite material	Switch ON/OFF at a trigger temperature by using two metal strips that have different thermal expansion coefficients which deform by temperature	Semiconductor (NTC) or Ceramic (PTC). Change in resistance due to temperature.

What is Thermorite?

How Does the Thermorite^® Reed Switch Work?

Figure 1. Reed switch operating principle (Source: KEMET)

a) Break-type Switch

The break-type switch consists of the Thermorite® cylinder that surrounds the reeds. At both ends of the cylinder are ring-shaped permanent magnets, as shown in Figure 2.

Figure 2. Structure of break-type sensor (Source: KEMET)

b) Make-type Switch

The make-type switch has a similar structure to the break-type, except for an additional spacer inserted in the middle of the Thermorite cylinder as shown in Figure 3.

Figure 3. Make-type switch structure(Source: KEMET)

Switch Type	Status below temperature set point (Thermorite is magnetic)	Status above temperature set point (Thermorite is non-magnetic)
Make	OFF. Contacts open	ON. Contacts closed
Break	ON. Contacts closed.	OFF. Contacts open

Table 2. Summary of switch status at temperatures above and below set point.

For more information about the Thermorite® Reed Switch, please vist the Resources section of this competition.

What kind of experiments can the participants perform with the Thermorite® Reed Switch?

Temperature control

White Goods (Home kitchen appliances)
Aquarium heater

Overheat Protection

Experimenting with Thermal Switches

About the Competition

In this design challenge, participants will be given a kit of thermal switches based on KEMET’s Thermorite^® to experiment with their use, application, response, and more.

Thermal Switch/Sensor	Thermorite^® Reed Switch	Bi-metallic Strips	Thermistors
ContactType	Mechanical	Mechanical	Electrical
Operating Principle	Switching the reed switch ON/OFF at a trigger temperature of the thermo-ferrite material	Switch ON/OFF at a trigger temperature by using two metal strips that have different thermal expansion coefficients which deform by temperature	Semiconductor (NTC) or Ceramic (PTC). Change in resistance due to temperature.

What is Thermorite?

How Does the Thermorite^® Reed Switch Work?

Figure 1. Reed switch operating principle (Source: KEMET)

a) Break-type Switch

The break-type switch consists of the Thermorite® cylinder that surrounds the reeds. At both ends of the cylinder are ring-shaped permanent magnets, as shown in Figure 2.

Figure 2. Structure of break-type sensor (Source: KEMET)

b) Make-type Switch

The make-type switch has a similar structure to the break-type, except for an additional spacer inserted in the middle of the Thermorite cylinder as shown in Figure 3.

Figure 3. Make-type switch structure(Source: KEMET)

Switch Type	Status below temperature set point (Thermorite is magnetic)	Status above temperature set point (Thermorite is non-magnetic)
Make	OFF. Contacts open	ON. Contacts closed
Break	ON. Contacts closed.	OFF. Contacts open
