マイクロスイツチ。 A common terminal, a normally open terminal, and a normally closed terminal are respectively fixed through the switch base, and the base end of a movable contact piece is rotatably pivoted to the common terminal in electrical contact. A switching contact at the free end is positioned between a normally open contact and a normally closed contact provided at each end of the normally open terminal and normally closed terminal, and the proximal end is rotatably supported on the switch base. In the micro switch, a reversing spring is suspended between the free end of the actuator and the movable contact piece, which biases the movable contact piece in a direction in which the switching contact contacts the normally closed contact. The actuator is positioned between a pair of mounting pieces for pivoting the movable contact piece formed at the switching side end of the actuator, a locking portion of the actuator is formed on both mounting pieces, and the reversing spring is A micro switch, characterized in that the micro switch is mounted opposite to a notch or hole formed in the center of the actuator.
