Here are a couple of interesting relays that I salvaged out of some older Dental X-Ray equipment. I am guessing they are 1960's era. The first one is a 24 VAC solenoid that uses a cantilever to switch between the activation of one SPDT micro switch or another.
The second relay that I want to show you is actually two relays set up in such a way that each one latches the other and each one resets the other. These are 120 VAC coils and they each have 3 PDT switch configurations so I guess it is a 6 pole double touch flip flop with set and reset inputs. As a bonus in these videos you get to hear my bad voice which is a result of an idiopathic paralysis of one vocal chord. The most serious result of this affliction is that I can no longer win arguments.
