The Toggle Switches on the front panel of your DMC20 are totally sealed, no amount of whatever liquid you spray on them will ever get onto the contact surfaces. Toggle Switch as an example, there are literally 1000's of these in many different configurations. The only thing you can do is to replace the switch, which appears to be somewhat easy if your tech savvy, if not take it to someone whom is. The switches appear to be mounted on a PCB rear-mounted to the faceplate using the switches as standoffs / mounting hardware. Spectral DMC20 Internal picture Best of luck Peter |
In studying the picture of the DMC20, I don't think the toggle switch has anything to do with your channel dropout issue. The switch on the front merely control relays that do the actual phase inversion of the output, so its my somewhat qualified guess that one of the relays, orange cubes located towards the rear of the PCB to the right behind the output terminals, or the two located in the center just behind these are at fault.
