Abstract

The invention provides a touch switch manufactured by a CD4013 digital integrated circuit. The touch switch consists of a 12V direct current power supply, a touch electrode M, a single stable circuit, a reset circuit, a double stable circuit, a level drive and a control circuit. A double D flip-flop integrated circuit CD4013 is adopted by the circuit to respectively be wired into a single stable circuit and a double stable circuit; the single stable circuit is used for reshaping the pulse width of a touch signal and ensuring the reliability of each touch action; and the double stable circuit is used for driving an NPN silicon transistor VT1 to switch on or switch off, and the NPN silicon transistor VT1 controls a relay J to absorb or release. The touch switch is totally manufactured by discrete components, and both the heavy current and the light current can be effectively isolated by the relay, thus, the loaded power supply can be alternating current and direct current, and the touch switch can be widely used in the fields of household appliances, industrial automation and the like; moreover, the touch switch overcomes the defects existed in the mechanical self-locking switch.

Description

technical field [0001] The invention belongs to the technical field of electronic control, and relates to a touch switch made with a CD4013 digital integrated circuit. Background technique [0002] The disadvantages of commonly used mechanical self-locking rocker switches or toggle switches are: the operation action varies from person to person, and the switch contacts are prone to vibration. Because the mechanical self-locking switch is continuously impacted by a long-term high current, the contacts of the mechanical self-locking switch are easily ablated and worn. In order to overcome various inherent defects of existing mechanical self-locking switches, it is necessary to design and manufacture a touch switch with self-locking function. [0003] The present invention realizes the control switch with self-locking function by using only a small number of ordinary components and one touch electrode, that is, the load circuit of the touch electrode is turned on when the fing...
