Abstract:
A microswitch comprising:a pressure bar having a first side and a second side; an actuator; and a cam rotatably coupled to a shaft, said cam having a fork disposed near a peripheral portion of said cam, said cam having a first contact surface and a second contact surface, said first and second contact surfaces intersect, said cam having a center and having a shape such that the distances between the center of said cam to said first and second contact surfaces are different; wherein said actuator is disposed near said first side of said pressure bar, said cam is disposed near said second side of said pressure bar such that initially said first contact surface is in contact with said second side of said pressure bar, and when said fork is pushed to cause said cam to rotate in a clockwise direction, said first contact surface of said cam moves away from said second side of said pressure bar, and said second contact surface of said cam comes into contact with said second side of said pressure bar and pushes said pressure bar against said actuator to activate said actuator.
