Multi-way Switch Circuit

This circuit can be used for staircase lights or for any device which may require to be controlled from several different locations.

Electronic Multi way Switch circuit

NOTE:

  • 12 volts positive line connect to R2 and RL1 common line, Other to GND line.
PARTS LIST
R11.4K
R2100Ω 0.5W
R310Ω 1W
VR1100Ω  Preset
D1IN4001
Z15V 0.5W zener
RL112V 200Ω
IC7493
T1SL100
LAMP230V LAMP

IC 7493 is wired as a bistable multivibrator here. Transistor T1 (SL100 or AC127) acts as a switch for the load.

When there is a current to the base of T1, it will conduct and activate the relay which can be a 12V, 200-ohm or 9V 200-ohm type.

VR1 is adjusted to get exact 5V at pin 5 of IC 7493.

Any number of push button switches can be connected in parallel to points X and Y.By just pressing any of these switches, the circuit works and the relay operates. The lamp will glow to confirm the switching.

When any of the parallel switches is pressed once again it will switch off the supply to the lamp automatically.


Please send your ideas, those are very important for our success…

      Sorry for my mistake. 12 volts positive line connect to R2 and RL1 common line, Other to GND line.

    thanks for sharing such a nice project, i have a question, why to make a multiway switch system using such an electronic circuit when we can make it using a simple switches of 3 ways and four ways for example? what this electronic system have and the simple mechanical system doesnt have? thanks a lot
