は、伸長状態にあるが、ばね11の付勢力により
ボール4が嵌合孔12に保持される力が復帰ばね
13の付勢力よりも大であるため、操作レバー8
は閉姿勢を維持する。 In the above configuration, when using switch 2
When switching from OFF to ON, grasp the knob 18 and move the actuator 15 toward the closed position against the return spring 13. Then, the operating lever 8 connected to the actuator 15 rotates clockwise about the rotation shaft 16, and its pressing portion 8a presses against the switch switching piece 2a. At this time, the actuator 15 slides inside the sliding case 10 against the return spring 13 and the compression spring 11, and the ball 4 is located in the fitting hole 12. Then, the ball 4 is fitted into the fitting hole 12 by the biasing force of the spring 11, and the switch 2 is maintained in the ON state. At the same time, the operating lever 8 is also pushed by the compression spring 11 and moves in the direction away from the substrate 1 together with the rotating shaft 16, as shown in FIG. 1b. At this time, the return spring 13
is in an extended state, but since the force with which the ball 4 is held in the fitting hole 12 by the biasing force of the spring 11 is greater than the biasing force of the return spring 13, the operating lever 8
maintains a closed position.
次に、スイツチ2をONからOFFに切換える場
合は、ON状態のつまみ18を握持してボール4
の保持力に打勝つて操作レバー8を開姿勢方向へ
若干移動させる。すると、作動子15の水平方向
の移動により作動子15に内装するボール4はば
ね11の付勢力に打勝つて嵌合孔12から離脱す
る。同時に、伸長されていた復帰ばね13の復元
力により操作レバー8が開姿勢Y方向へ一気に回
動し、スイツチ切換片2aから離間する。 Next, when switching the switch 2 from ON to OFF, grasp the knob 18 that is in the ON state and press the ball 4.
The operating lever 8 is moved slightly toward the open position by overcoming the holding force. Then, as the actuator 15 moves in the horizontal direction, the ball 4 housed in the actuator 15 overcomes the biasing force of the spring 11 and separates from the fitting hole 12. At the same time, due to the restoring force of the extended return spring 13, the operating lever 8 suddenly rotates toward the open position Y direction and separates from the switch switching piece 2a.
このように、スイツチ2のOFFからONへの切
換は、操作レバー8の引張力が復帰ばね13の張
力に勝ることにより行なわれ、またONからOFF
への切換は、復帰ばね13の復元力により行なわ
れるので、操作レバー8が途中で止まることがな
く、従つてスイツチ2の切換に対する使用者の誤
動作が防止され、切換は円滑に行なわれる。 In this way, the switch 2 is switched from OFF to ON when the tensile force of the operating lever 8 overcomes the tension of the return spring 13, and the switch 2 is switched from OFF to OFF.
Since the switching is performed by the restoring force of the return spring 13, the operating lever 8 does not stop midway, thereby preventing the user from erroneously operating the switch 2, and switching is performed smoothly.
なお、本考案は、上記実施例に限定されるもの
ではなく、本考案の範囲内で修正、付加され得る
ことは勿論であり、例えば上記実施例におけるボ
ール4は半球状等でもよい。 It should be noted that the present invention is not limited to the above-mentioned embodiments, and it goes without saying that modifications and additions can be made within the scope of the present invention. For example, the ball 4 in the above-mentioned embodiments may have a hemispherical shape or the like.
