Abstract
Provided is a switch that can reliably bring contacts into contact with each other with a small load, and can be prevented from malfunctioning. A switch is provided with a plunger, a lower torsion spring in which a biasing direction changes according to the movement of the plunger. The lower torsion spring biases the plunger in an opposite direction to a returning direction when the plunger is in the operation position, and biases the plunger in a direction different from the opposite direction to the returning direction when the plunger is in the reference position.
