Japanese Laid-Open Patent Publication No. 60-81719 and Japanese Utility Model Laid-Open No. 2-80929.
As disclosed in the publication, there is known a structure in which a coil spring incorporated in a housing with a slight inclination is buckled to rotate an actuator, and the actuator turns on a switch element such as a membrane switch. ing. That is, both ends of the coil spring are fixed to the stem and the actuator, and when the operator presses the stem for a predetermined stroke to compress the coil spring by a predetermined amount, the coil spring arranged at an inclination buckles, Since the actuator follows the buckling operation and rotates, the movable contact of the switch element is pushed into the actuator and comes into contact with the fixed contact. And
Since a click feeling is generated when the coil spring buckles, the operator can feel the switch-on with the fingers.

の復帰力により、ステムが筐体に沿って初期位置まで上
昇するとともに、アクチュエータが上記座屈時とは逆向
きに回転してスイッチ素子がオフ状態に復帰するように
なっている。When the pushing operation force on the stem is removed in the switch-on state, the stem is lifted up to the initial position along the housing due to the restoring force of the buckled coil spring, and the actuator does not move when the buckling occurs. Is rotated in the opposite direction to return the switch element to the off state.

具合があった。However, in the above-mentioned conventional push button switch, the buckling motion of the coil spring must be converted into the rotary motion of the actuator, and the rotary motion ensures the movable contact of the switch element. Since it has to be brought into contact with the fixed contact, the structure is complicated and the cost is inevitably increased.
