arduino M888 10Pcs KW12-3 Micro Roller Lever Arm Open Close Limit Switch Electronic Components Electronic Hobby Kit

Rated voltage: AC 125V-250V Current rating: 5A Diamension: 20 x 10 x 6mm (L X W X H) By external mechanical force transmission elements (by pins, buttons, levers, rollers, etc.) will be used to force action on a reed, producing reed instantaneous action when action shifted to the critical point, so moving contact with the fixed contact spring at the end of the action point fast on or off. When the force is removed on the drive components, action reed produce reverse action force transmission element reverse stroke when the action reaches a critical point reed, instantaneous reverse action. Apply in a computer mouse, car mouse, automobile electronic products, communications equipment, military products, test instrument, gas water heater, gas burner, small home appliance, microwave oven, electric rice cooker, floating ball supporting equipment, medical equipment, building automation, electric tools, ect.
