Abstract

An intelligent line switch and particularly a line switch equipped with an approaching or touching sensor, and an adjusting knob with a sensor of adjusting sensitivity. The line switch includes a switch operable in a manual mode or an automatic mode. The manual mode may control an electric device in a conventional way. When switched to the automatic mode, the sensor can detect approaching or touching of operator'"'"'s hand. Thus operator can easily actuate operations of ON or OFF or adjustment of the electric device by merely a single motion such as approaching or touching with one hand without the complicated operations of approaching, grasping, depressing and leaving occurred to the conventional line switches.

Claims

1. An intelligent line switch comprising a shell and a control device housed in the shell, the control device including an inductive circuit which has a sensor sensible to approaching or touching of an object, the control device being connected to one end of a power cord which further connects to a load through the control device;

wherein the control device controls ON or OFF of the load through a single motion when an operator'"'"'s hand approaches or touches the sensor.

2. The intelligent line switch of claim 1, wherein the power cord connects to a common contact of a selection switch for an automatic and a manual control modes before connecting to the control device, the automatic control mode having a first contact connecting to the control device, the manual control mode having a second contact connecting to a third contact located on one end of a button switch, the button switch having a fourth contact connecting concurrently to an output control end of the control device and the load.

3. The intelligent line switch of claim 1, wherein the shell is made from metal or selected conductive materials, the inductive circuit of the control device being connected to the shell so that the shell has induction capability to substitute the sensor.
