Patent ID: 8604376

Claim:
An electrical switch comprising: a body; at least one fixed contact and a moving contact supported by the body and arranged for movement between a first position, in contact with the at least one fixed contact, and a second position, not in contact with the at least one fixed contact; and an operating mechanism for operating the moving contact by moving the moving contact between the first and second positions, the operating mechanism including a second spring and a resiliently biased presser, resiliently pressed upon the moving contact by the second spring, and moving the moving contact between the first and second positions while riding, in one of opposite first and second directions, past a barrier associated with the moving contact, wherein the presser has opposite first and second sides corresponding to the first and second directions, and the operating mechanism includes a first spring having first and second parts acting on the first and second sides of the presser, respectively, to maintain the presser in a neutral position while permitting movement of the presser in a rearward direction, against urging by the first spring, as the presser reaches the barrier in a forward direction, thereby accumulating an additional forward biasing force in the first spring that is applied to the presser to assist the presser to move faster upon riding past the barrier.
