#40 Shop Talk - Wafer switch cleaning tips


In this video we look at several types of wafer switches. We then look at a method I use to clean these switches and bring them back to life. These switches are in many types of equipment. Lets look at what  we can do to repair these.

RobertoLG:
hmmm, nice! I was surprise how clean they got and without a brush, a big  :-+ lots to learn from you :)

SeanB:
Nice, wonder how it will work with the switch all greased up. Going to use that next time I have to clean a switch, thanks. Night work even better using an ultrasonic cleaner with the small plastic tub sittting in the water in it, faster and scrubs all the dirt off as well.  With the Bakelite remember to use some hot air ( 130c or so) for a while to dry it if the switch is used to switch HT, as the SRBP will have absorbed a lot of water, and will arc over.

Radio Tech:
Not sure how well it attacks grease.  Most of the time I spray with a little contact cleaner then put in the solution.
Your idea on the ultra sonic is nice.  As great as this stuff works any enhancements has to be a plus.
You do have to dry out the Bakelite, should had mentioned that in the video but slipped my mind.

Brumby:
I can't imagine the grease would really be affected much with this solution - but I'd be happy to be proven wrong.  I do think something more specific for cleaning greasy surfaces - such as a contact cleaner - used beforehand would be far more effective.

Ultrasonics might be useful - but if this process is done in 15 minutes as it is, I wouldn't be too inspired about pulling out my ultrasonic cleaner.
