This mechanism produces an instantaneous change in contact state the moment the trip point is reached — regardless of how slowly the actuator moves. Reversing the actuator to the reset point causes the contacts to snap back to their original position. The distance between the trip and reset points (known as hysteresis or differential travel) prevents multiple false triggers when the actuating object is subject to vibration, ensuring stable, repeatable performance in demanding applications.\u003c\/p\u003e\n\n\u003ch3\u003ePackage Contents\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e10 × Mini Micro Limit Switch (Roller Lever, SPDT, Snap Action)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cem\u003eNote: Due to lighting conditions and display settings, the actual color may vary slightly from the images shown.
