Patent attributes
A temperature-dependent switch having a housing with an upper part and a lower part, wherein a first and a second stationary contact are arranged on the housing, and a temperature-dependent switching mechanism having a movable contact member. In its first switching position, the switching mechanism presses the movable 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 movable contact member spaced apart from the first contact. A closing lock prevents the switch, once having opened, from closing again by locking the switching mechanism permanently in its second switching position in a mechanical manner. The closing lock comprises a substantially disc-shaped locking element and a first latching member, which, in order to lock the switching mechanism, interacts in the second switching position with a second latching member that is arranged on the movable contact member.
