Electric switch

Electrical switch, comprising:

• a common contact body;
• a pre-tensioned elastically deformable contactor comprising a leaf spring portion and contact fingers projecting from a plane of the leaf spring, the contactor being electrically conductively connected to the common contact body;
• an actuating member for elastically deforming the contactor;
• and
• a first selective contact body having contact surfaces and a second selective contact body having contact surfaces;
• and
• a switch housing;
• wherein
• at least one first finger of the contactor, under pre-tension of the contactor, is in contact only with the contact surfaces of the first selective contact body and at least one second finger of the contactor is not in contact with the contact surfaces of either the first or the second selective contact body when the actuator is in a first switch position, and the at least one second finger of the contactor is in contact only with the contact surfaces of the second selective contact body and the at least one first finger of the contactor is not in contact with the contact surfaces of either the first or the second selective contact body when the actuator is in a second switch position and the respective contact fingers slidingly engage the respective contact surfaces during movement of the actuator between the switch positions;
• the leaf spring portion of the contactor is substantially flat and extends in a longitudinal direction of the switch and the contactor also has a step-shape, U-shape or angular-shape portion;
• the common contact body and the first and the second selective contact bodies, in that order, are spaced from each other in the longitudinal direction of the switch;
• the contactor comprises proximate a first end of the contactor a fastening area, adjacent the fastening area a deformation area formed by a center portion of the step-shape portion, a bottom portion of the U-shape portion or an apex portion of the angular portion, and adjacent the deformation area and proximate a second end of the contactor a rigid actuating area;
• the contactor is fastened at the fastening area to the common contact body and to a base of the switch housing and is pre-tensioned so that the actuating area thereof is in contact with the actuating member;
• and
• the contact fingers extend from the actuating area.

An electrical switch, comprising:

• at least three contact bodies including a common contact body, a first selective contact body having at least one first contact surface and a second selective contact body including at least one second contact surface;
• and
• a contactor comprising an electrically conducting material connected in an electrically conducting manner to the common contact body, said contactor including at least one portion which is elastically deformable, said contactor further having a structural configuration which includes at least one first contact region and at least one second contact region that achieve cooperative conductive contact with a respective one of said first and second contact surfaces when said contactor is moved respectively between first and second switch positions by selective deformation of said at least one portion, wherein said at least one first contact region is in contact with the at least one first contact surface and said at least one second contact region not in contact with the at least one second contact surface when in the first switch position, and the at least one second contact region is in contact with the at least one second contact surface and the at least one first contact region is not in contact with the at least one first contact surface when in the second switch position, and the first and second contact regions slidably engage the at least one first contact surface and the at least one second contact surface, respectively, during movement of the contactor between the first and second switch positions.
