This is a right-angle latching SPDT ON-ON sub-miniature toggle switch with 3 horizontal PCB pins, rated to 125VAC 3A. The right-angle terminal design allows you to mount the switch directly to your circuit board while extending the toggle lever out through the side of your enclosure. The shaft requires a 5mm hole and has enough length to pass through to a panel up to around 3-4mm thick. The switch has a smooth finished section around the lever, so no nuts or washers are required (or included). With a little encouragement, we found these fit into 2.54mm protoboards no problem, and breadboards can kinda work but it's a bit hacky. Do not use these switches with mains voltages!
