A temperature-dependent switch (10) has a temperature-dependent switching mechanism (20) having a snap-action disc (21, 22), a housing which accommodates the switching mechanism (20) and has a lower part (19) and an upper part (12), at least two stationary contacts (34, 35) which are provided on the inner surface (29) of the upper part (12) and each of which is connected to an outer connection (15, 16) which is associated with said contact, and also a current transfer member (24) which is arranged on the snap-action disc (21, 22) and can be moved by said snap-action disc. The snap-action disc (21, 22) presses the current transfer member (24), in a temperature-dependent manner, against the two stationary contacts (34, 35) which serve as bearing areas (36, 37) for the current transfer member (24). A third bearing area (38) for the current transfer member (24) is provided on the inner surface (29). The current transfer member is an approximately round contact plate (24) which is provided, on its surface which faces the stationary contacts (34, 35), with a contact area (33) which is closed in a circumferential direction around an axis (39) of symmetry of the switch ( Fig. 2 ). |
