Abstract
A temperature-dependent switching mechanism for a temperature-dependent switch, comprising an electrically conductive contact member; a contact ring arranged around the contact member and movably mounted on the contact member; and a temperature-dependent bimetallic snap-action disc comprising a first through hole through which the contact member is passed, wherein the bimetallic snap-action disc is arranged on a first side of the contact ring and is movably mounted on the contact member.
Claims15
A temperature-dependent switching mechanism for a temperature-dependent switch, comprising:
- an electrically conductive contact member;
- a contact ring arranged around and movably mounted on the electrically conductive contact member;
- and
- a bimetallic snap-action disc comprising a first through hole through which the electrically conductive contact member is passed, wherein the bimetallic snap-action disc is arranged on a first side of the contact ring and is movably mounted on the electrically conductive contact member,
- wherein the electrically conductive contact member comprises a bearing section extending along a longitudinal axis, a head section at a first axial end of the bearing section, and a foot section at a second axial end of the bearing section opposite the first axial end,
- the contact ring and the bimetallic snap-action disc being supported on the bearing section for axial movement relative to the bearing section along the longitudinal axis between the head section and the foot section, and
- the head section and the foot section defining axial end stops delimiting the axial movement.

A temperature-dependent switch, comprising:
- a temperature-dependent switching mechanism;
- and
- a switch housing surrounding the temperature-dependent switching mechanism and having a first electrical terminal and a second electrical terminal;
- wherein the temperature-dependent switching mechanism comprises:
- an electrically conductive contact member;
- a contact ring arranged around and movably mounted on the electrically conductive contact member;
- and
- a bimetallic snap-action disc comprising a first through hole through which the electrically conductive contact member is passed, wherein the bimetallic snap-action disc is arranged on a first side of the contact ring and is movably mounted on the electrically conductive contact member;
- wherein the temperature-dependent switching mechanism is configured to establish an electrical connection between the first and the second electrical terminal below a response temperature of the bimetallic snap-action disc and to interrupt the electrical connection upon exceeding the response temperature,
- wherein the electrically conductive contact member comprises a bearing section extending along a longitudinal axis, a head section at a first axial end of the bearing section, and a foot section at a second axial end of the bearing section opposite the first axial end,
- the contact ring and the bimetallic snap-action disc being supported on the bearing section for axial movement relative to the bearing section along the longitudinal axis between the head section and the foot section, and
- the head section and the foot section defining axial end stops delimiting the axial movement.
