Miniature Microswitch with Lever SPDT — 2A @ 125VAC, Snap-Action, PCB Mount (5-Pack)

Miniature Microswitch with Lever SPDT — 2A @ 125VAC, Snap-Action, PCB Mount (5-Pack)

These miniature SPDT microswitches with levers are the standard snap-action switch for limit switch, end-stop, and position detection applications. The lever arm extends the actuation point away from the switch body, allowing the switch to be triggered by a moving part, cam, or object without direct contact with the switch body. Three terminals (C, NO, NC) provide both normally-open and normally-closed contacts from a single switch. Pack of 5.
