Press light switch double circuit 7

A good performance is achieved with a two-wire connection for a double touch switch that can function even if there is a break in the left part of the line. This switch is designed for general lighting control, such as for decorative lighting. The switch consists of a control circuit that includes a neodymium tube (VD1 to VD-1), a crystal thyristor (VT3), and control transistors (VT1 and VT2). Typically, the thyristor (V113) is in an off state, meaning no current flows. The circuit operates on 220V AC, with VD-1 acting as a rectifier. When a person touches the M1 electrode, an induced current flows into the base of VT2, turning it on. This allows stored charge to activate VT3, lighting the lamp. When the M2 electrode is touched, the current flows to the base of VT1, triggering it and allowing the stored charge to discharge, which turns off the thyristor VT3 and extinguishes the lamp. The circuit includes anti-interference features to prevent malfunction due to supply voltage fluctuations. The components used include silicon diodes and a unidirectional thyristor. Proper wiring is essential, with the 220V AC mains phase and neutral line correctly connected to ensure normal operation. The load capacity is limited to 100W, making it suitable for incandescent bulbs and other small loads.

The circuit operates effectively as a touch-sensitive lighting control system, utilizing a two-wire setup to facilitate functionality even in the event of a line interruption. The primary components include a neodymium tube for rectification, crystal thyristor for switching, and transistors for amplification and control.

The neodymium tube (VD1 to VD-1) serves as the rectifier, converting AC voltage to a suitable DC voltage for the rest of the circuit. The thyristor (VT3) acts as the main switching device, which is triggered by the control transistors (VT1 and VT2). When the user touches the M1 electrode, the resulting induced current activates VT2, allowing it to conduct. This conduction triggers the thyristor VT3, which then powers the connected lamp.

The design includes a feedback mechanism where touching the M2 electrode causes current to flow to VT1, enabling it to conduct and discharge the stored charge from the capacitor. This rapid discharge results in the thyristor losing its trigger current, effectively turning off the lamp.

To ensure reliable operation, the circuit incorporates anti-interference measures to mitigate the effects of voltage fluctuations that could lead to unintended activation or deactivation of the lighting system. The choice of components, including silicon diodes and a unidirectional thyristor, is critical for maintaining performance and reliability.

The installation of this circuit requires careful attention to wiring, particularly the connection of the 220V AC mains phase and neutral line. Incorrect wiring may result in malfunction or failure to operate. The circuit is designed to handle a load of up to 100W, making it ideal for incandescent bulbs and small lighting applications, providing a convenient and efficient solution for touch-sensitive lighting control.A good performance is a two-wire connection of double touch off indiscriminately even a broken line in the left part of the line for the general lighting, flowers portion of li ght control switch, Ml to open cockles contact patch.
