Abstract

A wireless switch assembly, comprising: a wireless switch comprising a control switch; a wireless transmitter connected to the control switch and transmitting a corresponding control signal according to the instruction of the control switch; a first identification card pluggably mounted in the wireless switch and connected to the wireless transmitter; a wireless receiver connected to a controller of a controlled piece and communicating with the wireless switch through radio frequency signal or optical signal. The wireless receiver has a second identification card pluggably mounted therein. The present invention can achieve a remote control by a low power consumption wireless transceiver module and matches the wireless switch to the wireless receiver via the identification cards, thus eliminating the need for complicated control wiring, therefore greatly reducing the complexity of wiring, saving electric wires and cables, and reducing cost.

Claims

1. A switch assembly, comprising:

a wireless switch, comprising;

a control switch;

a wireless transmitter, connected with the control switch for transmitting a corresponding control signal according to an instruction from the control switch; and

a first pairing card, which stores an identity code is pluggably mounted in the wireless switch and is connected with the wireless transmitter, wherein the control signal carries the identity code; and

a wireless receiver, connected with a controller of a controlled component, communicating directly with the wireless switch via a RF signal or an optical signal, and comprising;

a second pairing card, which stores an identity code associated to the identity code stored on the first pairing code card and is pluggably mounted in the wireless receiver, wherein corresponding identity codes are previously set in the first pairing card and the second pairing card respectively, the wireless receiver first determines whether the identity code carried by the control signal communicated directly by the wireless switch matches the identity code set in the second pairing card after receiving the control signal from the wireless switch, and only when the identity code carried by the control signal matches the identity code set in the second pairing card, the wireless receiver feeds the control signal to the controller and the controller controls the controlled component according to the control signal, such that a pairing between the wireless switch and the wireless receiver is achieved by inserting the first pairing card and the second pairing card stored with associated identity codes into the wireless switch and the wireless receiver respectively.

2. The switch assembly according to claim 1, wherein the controlled component is a lighting device, and the controller is an electrical relay, a dimmer switch, a coupler or a thyristor for controlling the lighting devices.
