  • Auxiliary switch including cam operated, u-shaped leaf spring bridging contact arrangement
    Patent number: 5927485
    Abstract: An auxiliary switch arrangement is located inside a housing (1) and is equipped with at least two fixed contact pieces (2, 3, 4), with one connecting contact bridge (9, 10) which can be uncoupled in pairs from the contact bridge. The contact bridge (9, 10) is formed onto one end of a U-shaped curved leaf spring strip (11), transverse to the longitudinal direction of the leaf spring strip (11). The other, free end (12) of the leaf spring strip (11), is fastened inside the housing (1). The leaf spring strip (11) is pre-tensioned by the amount of contact pressure in the contact-making position of the contact bridge (9, 10). A slide (14) equipped with linear cams (15, 18, 19, 20, 21), which moves in a guide inside of the housing (1), lifts the movable contact pieces (17) off the fixed contact pieces (2, 3, 4) in the switched-off position. The slide (14) is actuated through an extension (16) by a switching device.
