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.

Power generation apparatus and wireless switch

A wireless switch includes a button member, a power generation module, an RF module, and a notification unit. The button member is mounted in a housing, and is configured to move. The power generation module is configured to generate power using energy produced by the movement of the button member. The RF module is connected to the power generation module, and is configured to transmit a switch signal using power generated by the power generation module. The notification unit is configured to operate using power generated by the power generation module. The RF module controls the notification unit in one or more notification states according to a strength or details of a reception state signal corresponding to the transmitted switch signal.

Wireless switch

A switch of high reliability in which built-in components are not detached even when a shock is applied to the switch. A microswitch is actuated by an operative plunger and LEDs are mounted on the same circuit board The switch is configured so that light from the LEDs is diffused and guided to an operation face on the upper side by the operative plunger A metal plate is attached into the internal space of the operative plunger According to this configuration, inward bending of the operative plunger due to a shock or the like is prevented from occurring, and engagement between engaging holes of a case and engaging protrusions of the operative plunger is prevented from being cancelled.
