Wireless switch

Control equipment for use in a system, the system comprising:

• a wirelessly controllable appliance, and
• a wired switch connected into a wired electrical circuit for supplying power from a power source to the wirelessly controllable appliance, the wired switch arranged to be switched from a first position to a second position by a user exerting mechanical force on a first area of the wired switch, and from the second position to the first position by the user exerting mechanical force on a second area of the wired switch,
• wherein one of the first position and the second position of the wired switch is an ON state in which the power is supplied from the power source to the wirelessly controllable appliance via the electrical circuit, and the other of the first position and the second position of the wired switch is an OFF state in which no power is supplied to the wirelessly controllable appliance via the electrical circuit;
• the control equipment comprising:
• a wireless switch arranged to be retrofitted to the wired switch, the wireless switch comprising one or more sensors, the one or more sensors arranged to detect whether the wired switch is in the first position or the second position and the one or more sensors further arranged to detect a touch input in at least a part of the first area of the wired switch and the one or more sensors further arranged to detect a touch input in at least a part of the second area of the wired switch, the wireless switch further comprising transmission circuitry arranged to transmit an indication of said detections, and
• a controller arranged to wirelessly control the wirelessly controllable appliance via a wireless communication channel, to receive the indication, and to determine a reachability of the wirelessly controllable appliance over the wireless communication channel, wherein the controller is further arranged to associate, based on the determined reachability of the wirelessly controllable appliance, one of the first area and the second area to an OFF command for turning OFF the wirelessly controllable appliance, such that the one area of the first area is the same area as the one of the second area which, when pressure is exerted on it, causes the wired switch to be switched to the position of the first and second position associated with the OFF state, and wherein the controller is further arranged for controlling the wirelessly controllable appliance, at least when the wired switch is in the ON state, to turn OFF when an indication is received of detection of a touch input in at least a part of the one of the first area and the second area associated with the OFF command.
