220V Touch Switch

This circuit is a 220V AC lamp touch dimmer. By simply touching the dimmer, it is possible to adjust the light intensity of incandescent lamps in three stages. The touch dimmer utilizes an 8-pin CMOS IC, specifically the TT8486A or TT6061A, which is designed for touch dimmer applications. When the mains switch is turned on, the lamp activates. The touch switch allows for the control of electrical devices without mechanical parts, thus preventing wear from mechanical contact. Touch switches are suitable for environments where standard switches may fail, such as in damp locations. Additionally, there is a 220V LED flasher circuit designed as a reliable alternative to thermally activated switches used for Christmas tree lamp flashing. This circuit is cost-effective and straightforward to construct. The schematic diagram includes the following components: R1 = 100K, R2, R5 = 1K, R3, R6 = 470R, R4 = 12K, C1 = 1000 µF 25V, D1-D4 = 1N4007, D5 = SCR P0102D, Q1 = BC327, Q2 = BC337, and SK1. This simple 220V light dimmer circuit can also be utilized to adjust the brightness of mains lights and control the speed of AC motors. It incorporates a triac, diac, and a radio-frequency interference (RFI) noise suppression circuit. The component part for R1 is 10K. Furthermore, there is a basic tachometer schematic that serves as a frequency converter circuit, which transforms the input signal into a proportional current measured by a pointer device. The deflection of the milliammeter corresponds to the frequency of the input signal. For installation, input pin A should be connected to a high-voltage wire in a car, while pin B connects to the ground.

This touch dimmer circuit operates on 220V AC and offers a user-friendly interface for adjusting the brightness of incandescent lamps. The core component, the TT8486A or TT6061A CMOS IC, facilitates the touch-sensitive control, making it ideal for modern applications where mechanical switches may be impractical. The design eliminates the need for physical buttons, reducing wear and enhancing durability, particularly in environments prone to moisture or dust.

The circuit's operation begins when the mains power is activated. The touch sensor detects the user's input and sends a signal to the IC, which processes the command and adjusts the output to the connected lamp. The three-stage dimming feature is accomplished through the use of a triac and diac, enabling smooth transitions between brightness levels. The inclusion of an RFI noise suppression circuit is critical for maintaining the integrity of the electrical system, minimizing electromagnetic interference that could affect nearby devices.

In addition to its primary function as a dimmer, this circuit can also be adapted for controlling the speed of AC motors, making it versatile for various applications. The schematic diagram provides a clear representation of the component layout and interconnections, ensuring ease of assembly for individuals with basic electronics knowledge. The components listed, including resistors, capacitors, diodes, and transistors, are standard and readily available, contributing to the overall cost-effectiveness of the project.

The tachometer schematic adds another layer of functionality, allowing for the measurement of frequency through a proportional current output. This feature is particularly useful in automotive applications where monitoring engine speed is essential. The connection points for the high-voltage input ensure accurate readings, reinforcing the circuit's reliability in practical use. Overall, this circuit represents a comprehensive solution for both lighting control and frequency measurement in electrical systems.Here the 220V AC lamp touch dimmer circuit. By only touching this touch dimmer you are able to increase the light intensity of incandescent lamps in three stages. The touch dimmer is designed all around 8-pin CMOS IC TT8486A/TT6061A especially produced for touch dimmer applications.

In the beginning, when mains switch is "on", the lamp. Turn on a nd turn off your electrical devices using touch switch, so you can "play" your electronic devices more fun. :). Touch switch don`t need mechanical part, so they will not worn out due to mechanical contact. Touch switches can be used in places where regular switches would not last, such as wet or.
