Abstract: The disclosure provides a socket that can easily secure internal insulation. The socket includes a box-shaped first housing and a second housing attached to the first housing. The first housing includes a first wall and a second wall. The first wall extends in a width direction that intersects an opening surface, and has a first opening for inserting a screw member that fixes a conductor part of a wire. The second wall extends in a direction that intersects the opening surface and the first wall, and has a second opening for inserting and removing the conductor part of the wire. The second housing includes a second housing body and a locking arm. The second housing body covers the opening surface. The locking arm extends from the second housing body in the width direction and is locked to the first housing in the width direction.

Abstract: A wireless switch includes a cover member, a button member, a first plunger, a second plunger, a trigger spring, a return spring, a shaft, a housing, and a power generation module. An intermediate member constituted of the first plunger, the second plunger, the trigger spring, the return spring, and the shaft is connected between the button member and the power generation module. The intermediate member prevents a position of the shaft making contact with the power generating shaft of the power generation module from changing, and causes stress to build up in the trigger spring, until a movement distance of the button member reaches a predetermined distance. The intermediate member releases the stress built up in the trigger spring and pushes the power generation shaft with the shaft using the released stress upon the movement distance of the button member reaching the predetermined distance.
