Abstract
A spring element for a temperature-dependent switching mechanism of a temperature-dependent switch. The spring element comprises a central portion having a convexly curved upper side and a concavely curved lower side, an annular support portion that surrounds the central portion and is separated therefrom by an annular gap, and a plurality of webs arranged in a circumferential direction. Each of the webs bridges the gap such that a radially inner end of the respective web is connected to a radially outer edge of the central portion, which extends in the circumferential direction, and a radially outer end of the respective web is connected to a radially inner edge of the annular support portion, which extends in the circumferential direction.
Claims17
A spring element for a temperature-dependent switching mechanism of a temperature-dependent switch, the spring element comprising:
- a central portion having a convexly curved upper side and a concavely curved lower side;
- an annular support portion surrounding the central portion;
- an annular gap separating the central portion from the annular support portion;
- and
- a plurality of webs distributed circumferentially around the central portion about a central axis of the spring element in a circumferential direction,
- wherein each web extends across the annular gap and has a radially inner end connected to a radially outer edge of the central portion, and a radially outer end connected to a radially inner edge of the annular support portion.
A temperature-dependent switch comprising:
- two external terminals;
- and
- a temperature-dependent switching mechanism configured to switch, depending on its temperature, between a closed switch state in which an electrically conductive connection between the two external terminals is established and an open switch state in which the electrically conductive connection is interrupted, wherein the temperature-dependent switching mechanism comprises a spring element comprising:
- a central portion having a convexly curved upper side and a concavely curved lower side;
- an annular support portion surrounding the central portion;
- an annular gap separating the central portion from the annular support portion;
- and
- a plurality of webs distributed circumferentially around the central portion about a central axis of the spring element in a circumferential direction,
- wherein each web extends across the annular gap and has a radially inner end connected to a radially outer edge of the central portion, and a radially outer end connected to a radially inner edge of the annular support portion.
