US Patent 7932475 Electric switch

An electric switch with flexible, fork-shaped contactor having an end area with first and second contact points. At least one tension strip and at least one arched section extends from the contactor in such manner that changing the switch from a normal position, in which the first contact point is in contact with a first contact surface, to a switched position, in which the second contact point is in contact with a second contact surface, and vice-versa, takes place by deformation of the tension strip while an angle formed at the transition, between the arched section and the end area of the contactor, remains substantially unchanged.
