Hi,
I have an illuminated rocker switch that was removed from the power supply of a tube guitar amp. The switch was acting as the main power switch and has three connections.
The switch was wired as follows - the AC input connected to the middle contact (2), while the outside contacts were connected to (1) ground and (3) the rest of the power supply circuit.
When I was looking at this in the circuit I thought it was odd as I expected one switch position to connect contacts (1) and (2) which would have shorted the mains to the chassis!
Now that the switch has been removed from the circuit I've checked it and there doesn't seem to be a position that connects contact 1 to either of the other two contacts. From what I can see the switch is SPST. Anyone know anything about switches like this one?
Cheers,
Chris
