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 between the two contacts via the contact member and, in its second switching position, keeps the contact member spaced apart from the first contact and thereby disconnects the electrically conductive connection between the two contacts and opens the switch. The switch further comprises a closing lock that, as soon as it is activated, prevents the switch once having opened from closing again by keeping the switching mechanism in its second switching position. 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 from a first shape, in which the locking element does not activate the closing lock, into a second shape, in which the locking element activates the closing lock by exerting a force on a part of the switching mechanism, which force holds the switching mechanism in its second switching position.

A flash double-temperature linkage temperature controller has an arrangement that enables contacts of two movable contact sheet sets and two static contact sheet sets to sequentially operate at different temperatures, and a desired fixed temperature difference is obtained. The two movable contact sheet sets are respectively connected to the two static contact sheet sets to control two electric heating tubes, so that the effect whereby two electric heating tubes (high power) work during water heating and a single electric heating tube (low power) works during heat preservation heating is achieved, and the working frequency of the high-power contact sets is greatly reduced.

A breaker is provided with a first terminal piece on which a fixed contact is formed, a movable piece with a movable contact for pressing the movable contact against the fixed contact so as to contact therewith, a thermally-actuated element deforming with a change in temperature and moving the movable piece so that the movable contact is separated from the fixed contact, and a second terminal piece electrically connected to the movable piece. The movable contact includes a first movable contact and a second movable contact arranged at a first end portion and a second end portion, respectively, of the movable piece in its longitudinal direction. The fixed contact includes a first fixed contact arranged at a position with which the first movable contact can contact, and a second fixed contact arranged at a position with which the second movable contact can contact.

The present disclosure relates to a thermal trip compensation structure including a tripping bar having an ejector pin, a bimetal strip, a compensating component, a support for the compensating component, and an adjustment component. One end of the bimetal strip is connected with the support. The support receives and supports the compensating component. The adjustment component is capable of adjusting a position of the compensating component relative to the support. The compensating component has an inclined slant surface which is set in such a way that a gap between the inclined slant surface and the ejector pin of the tripping bar when the bimetal strip is deflected after the occurrence of short circuit is less than the gap between the inclined slant surface and the ejector pin of the tripping bar when the bimetal strip is not deflected before the occurrence of the short circuit.
