Temperature-dependent switch with a current transfer member

摘要

A temperature-dependent switch comprising a temperature-dependent switching mechanism having a snap-action disc, a housing having a lower part and an upper part which accommodates the switching mechanism, at least two stationary contacts provided on the inner surface of the upper part, each of which is connected to an outer connection, and a current transfer member arranged on the snap-action disc that is moved by said snap-action disc. The snap-action disc presses the current transfer member, in a temperature-dependent manner, against the two stationary contacts which serve as bearing areas for the current transfer member. A third bearing area for the current transfer member is provided on the inner surface. The current transfer member is an approximately round contact plate having on its surface facing the stationary contacts, a contact area closed in a circumferential direction around an axis of symmetry of the switch.
