The central contact carrier (16) supports the bridging contact element and is set into the housing (7) together with the contact pins. The complete assembly is retained wth a panel opening by a ring shaped plate (5) secured by screws. ADVANTAGE - Providing robust, reliable switch actuation, capable of operation in wide temp. range (-30 deg.C to +80 deg.C).
