Switches and especially wire contacts used in switches

摘要

An electric switch apparatus includes a stationary base plate (2) and an actuating part (6) carrying an electrical conductor member (8) displaceable between at least two positions relative to the base plate. The base plate carries a plurality of elongate resilient contact members (14) adapted to engage the electrical conductor member (8). The conductor member includes a flat metallic electrically conductive material which is selectively brought into contact with the fixed resilient contact members held on the base member when the actuating part is displaced between said first and second positions. A first predetermined electrical connection between the fixed contact members is established when the actuating part is held in the first position. A second predetermined electrical connection between the fixed contact members is established when the actuating part is moved to the second relative position. The contact members are preferably formed as wire contacts having ends attached to the base plate and second free ends formed in the shape of a curved bow contact (12). The electrical conductor configuration is formed by a wiring wafer (8) which connects, electrically, in the two positions of the electrical part, the bow contacts of the wire contacts resting against same under an elastic resilient pre-stressed condition.
