Abstract

A protective switch for protecting a circuit includes an operating element or rocker switch, contact connections projecting from a housing, a contact spring electrically connected to a first contact connection and having a free end covering a second contact connection for making contact. A bimetallic element in the housing runs transversely to a slider longitudinal direction and is electrically connected between the first contact connection and through the contact spring to the second contact connection. A slider slides in the housing and has a contact end bearing against and acting upon the contact spring counter to its restoring force in a contact position. The slider is latched by the operating element in a turned-on position. The bimetallic element is coupled to the slider for thermal tripping and has a first longitudinal section at least partly covering and unlatching the slider upon overcurrent to break contact, and a second longitudinal section.
