Abstract: A temperature-dependent switch comprising first and second stationary contacts and a temperature-dependent switching mechanism having a movable contact member. The switching mechanism, in its first switching position, presses the contact member against the first contact and thereby produces an electrically conductive connection and, in its second switching position, keeps the contact member spaced apart from the first contact and thereby disconnects the electrically conductive connection. The switch further comprises a closing lock that, as soon as it is activated, prevents the switch once having opened from closing again. The closing lock comprises a locking element having a shape-memory alloy and an opening through which the movable contact member protrudes. The locking element is configured to change its shape upon exceeding a locking element switching temperature and activate the closing lock, which holds the switching mechanism in its second switching position.

Abstract: A temperature-dependent switch comprises a first stationary contact, a second stationary contact, and a temperature-dependent switching mechanism having a movable contact member. In its first switching position, the switching mechanism presses the contact member against the first contact and thereby produces an electrically conductive connection between the two contacts.

The temperature-dependent switching mechanism further comprises first and second temperature-dependent snap-action parts which switch from geometric low-temperature configurations to geometric high-temperature configurations when exceeding first and second switching temperatures, respectively, and switch back when subsequently falling below first and second reset temperatures, respectively.

Abstract: A temperature-dependent switch comprises first and second stationary contacts and a temperature-dependent switching mechanism having a movable contact member and a temperature-dependent snap-action part, which transitions between geometric low- and high-temperature configurations based on a temperature of the switch. Switching the snap-action part from its geometric low- to high-temperature configuration moves the switching mechanism from a first to a second switching position and thereby opens the switch. A closing lock prevents the switch once having opened from closing again by keeping it in its second switching position. The closing lock comprises a fusible medium which melts when a melting temperature of the medium is exceeded, contacts, in a molten state, a part of the switching mechanism when it is in its second switching position, and solidifies again and thereby locks it in its second switching position when the temperature of the switch falls below the melting temperature of the medium again.

Abstract: A temperature-dependent switch which comprises a first and a second stationary counter contact and a temperature-dependent switching mechanism having a current transfer member. The switching mechanism, depending on its temperature, either closes the switch by pressing the current transfer member against the first and the second counter contact and thereby establishing an electrically conductive connection between the two counter contacts via the current transfer member, or opens the switch by keeping the current transfer member at a distance from the first and the second counter contact and thereby interrupting the electrically conductive connection. A closing lock is provided, which keeps the switch open when it has been opened for the first time. The closing lock comprises a spring washer which directly interacts with the current transfer member and mechanically locks the latter permanently when the switch has been opened for the first time so that the switch remains permanently open.
