A switch device includes an actuation unit, a movable unit, a first base, and a second spring, which is a torsion coil spring that acts between the actuation unit and the movable unit. The movable unit is movable with respect to the base. The second spring applies a force to the actuation unit when the actuation unit is at a third position in a direction that is not parallel to a direction in which the torsion coil spring applies a force to the actuation unit when the actuation unit is at a fourth position.

In one example, an electronic device may include an electronic switch connected to a power supply, a controller connected to the electronic switch, an electromagnetic generator connected to the controller, and a power button coupled to the electro-magnetic generator. The electromagnetic generator may generate an induced current when the power button is pressed. Further, the controller may receive the induced current and output a control signal to the electronic switch to enable the electronic switch to control the power supply to the electronic device.

An operating device is provided for a human-powered vehicle. The operating device basically includes a base, a first operating member and a first electric switch. The first operating member is movably arranged with respect to the base from a first position to a second position. The first electric switch is provided to the base. The first operating member is configured to activate the first electric switch at least two distinct times in response to a progressive movement of the first operating member from the first position towards the second position.

A self-power wireless switch according to an embodiment of the present disclosure includes a lower body, an upper body rotatably coupled to one side of the lower body through a rotating shaft, a printed circuit board (PCB) comprising a contact unit which is coupled to the upper body and is in contact with a switch member pressed by a user, and a generator disposed on a bottom surface of the PCB and supplying power to the PCB. When the user presses the switch member, while the upper body rotates, a pressure is applied to a generator bar disposed on the generator to generate power.

A self-powered switching device is provided. In embodiments, the device uses a prestressed flextensional electroactive member to generate a signal for activation of a latching relay. The electroactive member has a piezoelectric element with a convex face and a concave face that may be compressed to generate an electrical pulse. The flextensional electroactive member and associated signal generation circuitry can be hardwired directly to the latching relay or may be coupled to a transmitter for sending an RF signal to a receiver which actuates the latching relay.

The present invention provides a switch which allows a communication module to be made waterproof while maintaining a switch function. A wireless switch device which functions as a rocker switch includes a cover member and an elastic waterproof member both of which seal an opening of a casing member in a state in which a wireless switch module is housed in the casing member. The wireless switch device further includes a seesaw-shaped member which is arranged on an outer side of the cover member and the waterproof member which outer side is opposite to a side on which the wireless switch module is sealed with the cover member and the waterproof member.

A switch device (10) and method for generation of energy for operating the switch device (10), wherein the switch device (10) is provided with a drive unit (120) interacting with an actuation device operable by a user, and with a moving device (130) configured to be set in motion by the drive unit (120), and with an energy harvester (132, 140, 140a) for providing energy to the switch device (10) in dependence on a motion of the moving device (130), such that energy for commands or other operations is provided to the switch device (10). The moving device (130) is configured to be repeatedly repositioned in relation to a defined zero position, as long as it has kinetic energy, in order to provide kinetic energy which can be converted in electric energy by the energy harvester (132, 140, 140a). Such an electromechanical device for generating energy can ensure wireless operation of the switch device (10) without the need of batteries or any other kind of power supply.
