Abstract

The invention relates to a simple and reliable touch control switch. The simple and reliable touch control switch consists of a 12-V direct-current power supply, a one-way silicon controlled rectifier 1 (SCR1) trigger circuit, a one-way silicon controlled rectifier 2 (SCR2) trigger circuit, a relay control circuit and a load RL circuit. A conventional mechanical self-locking rocker switch or a toggle switch has the defects that actions are mechanical, operating actions are different because of persons, a contact is easy to jitter, a contact is easy to ablate, abrade and the like. The touch control switch is realized by only using a small number of common components and two touch metal pieces, namely an on-load circuit is switched on by touching a touch electrode once, and an off-load circuit is switched off by touching the touch electrode once. The overall touch control switch is made of discrete components, and strong electricity can be effectively isolated from weak electricity through a relay, so that the power supply of a load can use alternating current and also can use direct current. Therefore, the touch control switch has a certain function in the field of household appliances, industrial automation, and optical, mechanical and electrical integration.

Description

technical field [0001] The invention belongs to the technical field of electronic control, and relates to a simple and reliable touch control switch. Background technique [0002] The disadvantages of mechanical self-locking rocker switches or pull switches are: the action is mechanical, the operation action varies from person to person, and the switch contacts are prone to jitter. 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 worn and ablated. In order to overcome the inherent defects of the existing mechanical self-locking switch, the present invention designs and manufactures a touch control switch with self-locking function. [0003] The invention only uses a small number of common components and two touch electrodes to realize the control switch with self-locking function, that is, the “on” load circuit of the touch electrode is connected once, and the load ...
