Document Type and Number:
Japanese Patent JP2016136465
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a power supply changeover switch capable of resolving a problem of deterioration of a copper plate caused by welding heat even when the copper plate is used as a movable contact, and of equalizing contact pressures of an A-side and a B-side.SOLUTION: There is provided a power supply changeover switch that rotates a cross bar 11 comprising a movable contact 15 and pressure-contact springs 16 and 17 for the same to switch the power supply. On both surfaces at a front end part of the movable contact 15, an A-side contact 22 and a B-side contact 23 are caulk-fixed so as to be parallel in a width direction of the movable contact 15. The pressure-contact spring 16 for the A-side contact is arranged at the same side in the width direction as the A-side contact 22 of the movable contact 15. The pressure-contact spring 17 for the B-side contact is arranged at the same side in the width direction as the B-side contact 23 of the movable contact 15.SELECTED DRAWING: Figure 4
