Title:
SWITCH
Document Type and Number:
Japanese Patent JP3609704
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a switch which can prevent a moving-electrode from turning by a large amount beyond a prescribed release position.
SOLUTION: This switch 11 has bushings 21 and 22 relative in each phase piercing through and supported by both sidewalls of a body case 12, a fixed electrode 23 is provided inside the bushing 21 and a movable electrode 26, which can approach and leave the fixed electrode 23, is provided inside the bushing 22 with its rotation possible. In this case, a cushion 52, which prevents the movable electrode 26 from overrun by making the movable electrode 26 open- circuit collide, is supported via an insulating barrier 41 in the body case 12. For this reason, it is possible to prevent he moving-electrode 26 from turning by a large amount beyond the prescribed release position at open-circuit times.
