Thermodynamic relay

A contact reversing mechanism for switching contacts according to the present invention is provided with a movable plate (23) which is disposed on a reversing mechanism support part (20) so that one end is a fulcrum and the other end is swingable, and on one surface a movable contact (30a) among the contacts is provided. The reversing mechanism support portion includes: V-shaped support grooves (36a, 37a) formed in a pair of first movable plate holding arms (36, 37) extending in parallel and on which one end of the movable plate (23) is placed as a fulcrum; and a second movable plate holding arm (38) which extends from the first movable plate holding arm, is abutted against the other end side of the movable plate, and supports the movable plate in a state that the movable plate is inclined by a certain inclination amount. 本发明的切换触点的触点反转机构具有可动板(23)，该可动板(23)以一端为支点且另一端侧可摆动地配置于反转机构支承部(20)，在一个面上设置有触点中的可动触点(30a)。反转机构支承部包括：V字形的支承槽(36a)、(37a)，其形成于平行延伸的一对第一可动板保持臂(36)、(37)，供可动板(23)的一端作为支点载置；第二可动板保持臂(38)，其从第一可动板保持臂延伸，供可动
