ことを特徴とするサーモスイッチ。The center piece of the movable spring plate formed in a U-shape is fixed at one end of the base, and movable contacts are provided on the lower surfaces of the free ends of both sides of the movable spring plate, and these both sides are connected to the first movable side. spring,
A second movable spring is provided at the other end of the base, and a fixed contact is provided corresponding to each movable contact and contacts the movable contact with the elastic force of each movable spring, and a fixed contact is provided on the other end side of the base to contact the movable contact with the elastic force of each movable spring. In between, there is a first bimetal plate that reverses when the ambient temperature rises abnormally and pushes the free end side of the first movable spring upward, and a second movable plate that reverses at a predetermined upper limit of temperature lower than the abnormal temperature. A second bimetallic plate that pushes the free end of the spring upward and returns to its original state at a predetermined lower limit of temperature is arranged, and the free end of the first movable spring is provided with a step wall erected on the base when it moves upward. In a thermoswitch which is provided with a non-returning means that engages with a step and prevents the return, and which conducts electricity between the fixed contacts, a narrow part of the first movable spring extends slightly backward from the part where the movable contact is provided. 1. A thermoswitch comprising: a protrusion protruding from the upper surface of the base, the upper end of which abuts the lower surface of the narrow portion at a position slightly forward of the base thereof.
