WIPO Patent Application WO/2022/102707
Kind Code:
A1
Abstract:
The present invention sufficiently wipes a contact surface at the time of switching contacts to peel an insulator coating off the contact surface. A microswitch 1 is provided with: a movable member 6 having a movable contact 6a on one end with the other end swingably supported by a support frame 30, the movable contact 6a being capable of contacting first and second fixed contacts 5b and 4b which are arranged so as to be spaced apart from each other and which are fixed to a base 2; an actuator 7 for subjecting the movable member 6 to a reversal operation so as to move the movable contact 6 from the first fixed contact 5b side to the second fixed contact 4b side; and a tension spring 8 for causing a tensile force to act on the one end of the movable member 6. The support frame 30 is arranged across the tension spring 8 on both sides thereof. A first end portion 30A1 of the support frame 30 on one side of the tension spring 8 is fixed to the base 2, and a second end portion 30B1 of the support frame 30 on the other side of the tension spring 8 is not fixed to the base 2.
