BK1103A Switch Help

kas.lewis

I recently bought a second hand function generator and after checking it out it all appears to work well except for some of the switches. I was therefore hoping someone may be able to help me identify the make and model of the used switches. If I can replace them then I will have a perfectly good function generator, well minus the calibration (1993...)

This is a picture of the switch I 'm looking to replace. It's a six pin switch and appears that the upper and lower center are the two poles and the outer terminals are the four throws.

The function generator in question, awaiting its repairs.

 

Thanks

  • I'm wondering if a good clean and lube won't bring back the switches to their former glory.

     

    It's entirely likely that the contacts that were uncovered have suffered from oxidation, and with cleaning and manipulation might bring them back.

    A further spray of a lubrication type compound will ensure they remain in good condition.

    I was wondering about cleaning out the old switches and that in some ways would be the best solution. The question I had was how to go about opening them without damaging them. In some ways I don't have much to loose on the other hand it sort of kinda works... (Read as chicken). That might just be the best bet. I'll look into this option when  get a few minutes of downtime.

    Well, some contact cleaner is pretty "volatile", and liquidy, so you can just soak the whole switch assembly through the cracks while pushing the switch continuously so the contacts "rub" away any of the oxide. You can spray through open cracks if you can find any ... excess eventually evaporates.

     

    This can work, although I've found on some older switches, can be a little temporary as well.
