に設けられたことを特徴とする温度センサー。 The switch includes a shape memory alloy that constitutes one contact point, and a mover that constitutes the other contact point of the switch, and the shape memory alloy receives heat from an object to be measured or a space to be temperature measured to set a predetermined setting. When the temperature reaches the temperature, a part of the alloy deforms into a memorized shape and is in contact with the movable element in a fixed position, and the movable element transforms the part of the shape memory alloy from the fixed position to the shape memory alloy before the deformation. 1. A temperature sensor, characterized in that the temperature sensor is movable back and forth until it comes into contact with the part, and is always biased in the direction of returning to the home position by a spring or other elastic body or a magnet.
