Application: Apply in A computer mouse, car mouse, automobile electronic , communications equipment, , test instrument, gas water heater, gas , small home appliance, oven, electric rice cooker, floating ball supporting equipment, equipment, building automation, electric tools, . Operating temperature: -40 Celsius to 70 Celsius Rated voltage: AC 125V-250V Current rating: 5A Size: 20 x 10 x 6mm (L X W X H) PCB Terminals Circuit Board With Roller Lever Limit Working principle: 1.By external mechanical force transmission (by pins, buttons, levers, rollers, etc.) will be used to force action on a reed, 2.Producing reed instantaneous action when action shifted to the critical , 3.so moving contact with the fixed contact spring at of the action fast on or off. 4.When the force is removed on components, 5.Action reed reverse action force transmission reverse stroke 6.The action reaches a critical reed, instantaneous reverse action. Feature: contact spacing is small,short stroke action,according to the power of small,fast-break colour:black + red Material:PC+ metal Package Contents: 10 * -roller switches Only the above package content, other are not included. Note: Light and different displays may cause the color of the item in the a little different from the real thing. The measurement allowed error is +/- 1-3cm.
