Abstract

The invention is a touch-sensitive switch with brightness-control for lamps. The switch consists of a switch body and a switch shell. The switch body comprises a brightness-control and touch-sensitive board, a brightness-controlling circuit and a luminous device. A touch-sensitive conductive thin film is on an outer surface of the brightness-control and touch-sensitive board. The luminous device is beneath the brightness-control and touch-sensitive board. Input of the luminous device is connected to output of the brightness-controlling circuit. There are electrode leading wires on the brightness-control and touch-sensitive board, which are serially connected to the brightness-controlling circuit. The switch of the invention is convenient to use and easier to manufacture. It can be used to control the brightness of one or multiple lamps and to function as a position indicator and light for gloomy or dim environments.

Claims

1. A touch-sensitive switch with brightness-control for lamps comprising a switch body and a switch shell, the switch body comprising:

a brightness-control and touch-sensitive board having an outer surface and a inner surface;

a brightness-controlling circuit;

a luminous device beneath the inner surface of the brightness-control and touch-sensitive board, wherein input of the luminous device is connected to output of the brightness-controlling circuit;

a touch-sensitive conductive thin film on the outer surface of the brightness-control and touch-sensitive board; and

electrode leading wires serially connecting the brightness-control and touch-sensitive board and the brightness-controlling circuit.

2. The switch according to claim 1, wherein the luminous device is an electroluminescent screen (EL) or other luminous element.

3. The switch according to claim 1, further comprising a shielding layer beneath the inner surface of the brightness-control and touch-sensitive board.

4. The switch according to claim 3, wherein the shielding layer is a conductive thin film on the inner surface of the brightness-control and touch-sensitive board.

5. The switch according to claim 1, wherein the brightness-control and touch-sensitive board is made of glass, plastic or metal material.

6. The switch according to claim 4, further comprising a connection part connecting the electrode leading wires and the brightness-control and touch-sensitive board, wherein the connection part is a pressure connection part connected to the touch-sensitive conductive thin film on the outer surface of the brightness-control and touch-sensitive board and the conductive thin film shielding layer on the inner surface of the brightness-control and touch-sensitive board.

7. The switch according to claim 1, wherein the touch-sensitive conductive thin film on the outer surface of the brightness-control and touch-sensitive board is divided into more than one isolated block, wherein each block is serially connected to a brightness-controlling circuit and wherein the output of each brightness-controlling circuit is connected to an object to be controlled thereby.
