  • Patent number: 10453634
    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.

  • Patent number: 10304639
    Abstract: 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.

  • Patent number: 9865414
    Abstract: A limit switch is provided that is returned to an original position even if a turning angle of a turning lever becomes 90 degrees. In a section perpendicular to a turning shaft, a cam is formed such that a whole contact surface of the cam with a cam receiver is located on a side of the cam receiver with respect to a shaft center of the turning shaft when the external force does not act on the turning lever.

  • Publication number: 20170263393
    Abstract: A limit switch device is placed at an intended stop position, without the need to move the actuator additionally from the position at which the on/off state is switched. A first movable portion (211) causes a first contact to slide on a second contact in a switch mechanism (103) included in a microswitch by applying a force (F?) via an actuator (102a) and a plunger (102b).

  • Patent number: 9698662
    Abstract: A power-generating module has a base, a power-generating unit that is placed in the base, a plunger that is placed in the base and that vertically reciprocates, and a drive section that interlocks with the reciprocation of the plunger and starts up the power-generating unit. The drive section is biased to a boost-up position where the plunger is boosted up. The drive section has at least two links that turn between the boost-up position and a press-in position where the power-generating unit is started up. Both ends of one of the links are turnably supported by the base. Both ends of another link are turnably supported by the plunger. The links turn in an interlocking manner by coupling to each other.
