I am almost feeling kind of dumb at this moment because I do know some about electronics and testing some parts but this switch has stumped me when testing with my ohm meter.
The switch is a two part push/pull. The front part operates the KV voltage of my unit with the switch pushed in. The rear part of the switch operates the uA of my unit and between the two adjustments you have control of how the powder sticks to the metal part I am coating.
From time to time my settings for the KV want light up and after messing with the switch it will work like it should?
If I try to raise my uA's up then they will just drop and I will have to turn the knob back and start again. I can not get it to go as high as I need it to do sometimes. There might also be something wrong on my circuit board but I want to figure out this switch first and if it is bad then I can replace it.
On the back of the switch there are 4 lugs. Two of them are wired and the other two are not and I have tested them and they are separate from each other. When I test with the meter they test the same. They might start out with the ohm meter reading .6 and then go to .2 or .1 and when turning the knob I am seeing no change in the readings? If I cut the unit on and pull the knob to activate that part of the switch I can adjust the uA but just not as much as I need.
I am accustomed to seeing more movement of ohms when using an ohm meter than I am getting and at this point not getting any. Is it me or is it the switch and the switch just wont read like I think it should? I can not make out the numbers on the switch so can't try to look it up. Looking at the info and picture for the org switch this one has been replaced I think? This unit is old and finding parts is not going to be easy and the part numbers for this switch are not to be found except one that sold on eBay a few years back.
Here is a picture of the switch if tha helps anyone.
Thanks
