4 results about "Wireless remote-control switch" patented technology

A wireless remote-control switch is an electric switch which is controlled by a radio or other signal and does not require an operator to touch the switch. The remote-control device, if electrically operated, uses batteries with a low, safe, voltage. Such a switch avoids the risk of electric shock if a user touches a switch with wet hands, and allows switching apparatus from a location without a wired switch.
