Abstract: A temperature-dependent switch has two connection electrodes mounted on an insulating support as well as a switching mechanism that, as a function of its temperature, creates an electrically conductive connection between the two connection electrodes. Also provided is a resistance element that is connected to the two connection electrodes electrically parallel to the switching mechanism and is inserted into the insulating support perpendicular to the connection electrodes, so that it sits inside the insulating support and is retained by it.

Abstract: A temperature-dependent switch (10) comprises a bimetallic switching mechanism (12) that is arranged in a housing (11) having a first housing part (14) made of insulating material and a second housing part (17). The bimetallic switching mechanism (12) is connected to a first electrode (16) that is guided out of one housing part (14), and coacts with a second electrode (19) that is provided internally on the other housing part (17).

There is provided laterally on the spring element (23) a retaining extension piece (25) at which it is attached to the first electrode (16).

Abstract: An apparatus (10) for protecting an electrical device comprises two temperature-dependent switching mechanisms (12, 13) each having at least two temperature-dependent switch conditions, and three external terminals (15, 16, 17). The two switching mechanisms (12, 13) are arranged directly in a common housing (21) in such a way that each switching mechanism (12, 13), as a function of its temperature, connects a first or second external terminal (16, 17), associated with it, directly to a third external terminal, serving as center terminal (15), that is common to both switching mechanisms (12, 13).

Abstract: A switch having a housing which receives a temperature-dependent switching mechanism is described, the housing having an electrically conductive lower part as well as an electrically insulating cover part, closing off the lower part and attached thereto, on whose inner side a first countercontact, to which through contact is made externally, is provided for the switching mechanism. The lower part serves as the second countercontact of the switching mechanism and creates, as a function of its temperature, an electrically conductive connection between the two countercontacts. Arranged on the cover part in lossproof fashion are a first connection electrode that is connected electrically to the first countercontact, as well as a second connection electrode that is electrically connected to the lower part as a consequence of the attachment of the cover part to the lower part.

Abstract: A switch comprises a housing which receives a temperature-dependent switching mechanism and has a lower part on whose inner base a first countercontact for the switching mechanism is arranged. Also provided is a cover part, closing off the lower part, on whose inner side a second countercontact for the switching mechanism is provided. The switching mechanism creates, as a function of its temperature, an electrically conductive connection between the two countercontacts, to which contact can be made from outside. The lower part is made of insulating material, and contact can be made from outside with the first countercontact through a wall of the lower part. The cover part is made of electrically conductive material and simultaneously acts as the second countercontact, the cover part being held on an upper rim of the lower part.

Abstract: A temperature-sensitive switch (10) for protecting electrical parts against excess temperature and/or excess current comprises a bimetallic switching device (14) which opens or closes its contacts in response to an excess temperature. Said switching device (14) is contained in a casing (17) having a pot-like bottom part (18) and cover (19). A first heating resistor (15) is connected in circuit with the switching device (14) such that it locks the switching device (14) in a self-holding manner when said switching device (14) is actuated in response to an excess temperature. A second heating resistor (16) is connected in circuit with said switching device (14) and produces heat in response to a current flow therethrough. When an excess current flows through the second heating resistor (16) the switching device (14) is actuated. Both, the first and second heating resistors (15, 16) are integrated in said cover (19) of said casing (17).
