About This Microswitch
This microswitch is great for replacing your supply tray microswitch.
Basic Installation Instructions
Connect the positive from your battery or transformer to the common 'C' post on the switch. Then connect a wire to the normally closed 'NC' post or the normally open 'NO' post on the switch and that wire will be connected to the side of each light bulb. Run the negative from the battery or transformer to the bottom of the light bulbs.
If you are unsure of any of these steps, our electronics manuals cover installation of these parts in detail.
