Roller Lever Arm Mini Limit Switch ME8104

A snap-action microswitch used to detect when something has reached a physical position. The snap mechanism is what makes it reliable: the contacts change over abruptly at a precise point rather than drifting slowly, which gives a clean signal and repeatable trigger position. Used for end stops on machinery, door position sensing, safety interlocks and 3D printer homing. Snap action gives a clean, precise trigger point; Highly repeatable actuation position; Both normally open and normally closed contacts; Long mechanical life under repeated operation
