Abstract
The utility model discloses a touching type desk-lamp switch, and comprises an ac power supply, a power supply circuit, a switch execution circuit and a bulb. The switch execution circuit comprises a first inverter, a second inverter, a third inverter, a first resistor, a second resistor, a third resistor, a first capacitor, a second capacitor, a relay, a transistor, a diode and a touch pad. When a film is touched by a hand, body resistance enables an input pole of the first inverter to be connected with the first capacitor, so that a desk lamp is switched on; when the film is touched again, the human resistance enables high level of the first capacitor to be transmitted to an output pole of the first inverter, so that the first inverter outputs low level, and the desk lamp is switched off. According to the utility model, the inverters are used for controlling the switch, and the touching type desk-lamp switch has the advantages of simple circuits, easy preparation, and stable performance.
