In this post I will show you how to make toggle switch using 4013. So you can use a push botton as a switch with a 4013. This circuit can be used for switching on/off electronic devices such as lamp, fan, relay etc
Ic 4013 consist of 2 sets of D flip flop, You can use either a flip flop or both. Read What Is D Flip Flop And How It Works?
What is a toggle?
Toggle is switching from one condition to another in this case is or on of.
This is different from normal switches. On a normal switch if you press the switch the electric current will flow but when you release the switch the electric current will stop flowing. Read definition and types of switches in electronic circuits
By using this circuit you can turn on/off the electrical equipment using only a momentary pulse. Once it is on, it remains on till you press the switch again. If you press the switch once again it will make the circuit become of. Similarly, if the switch is pressed next
4013 Toggle Switch Circuit
To make this circuit you need some electronic components
- cmos 4013
- 5-12 VDC power supply. Read How to make a power supply?
- a push button switch
- 1 K resistor. Read what is a resistor?
- Led (light emitting diode)
This circuit has many functions
- Turn on/off electrical equipment using a momentary electric current
- can be used to create an asynchronous counter
- to divide the square wave frequency into half in a digital circuit
- save 1 bit data
The 4013 toggle switch circuit above will work like a general toggle switch
If you only use on of the D flip flop from this IC, the input leg on the unused switch must be connected to ground
You can connect out pin with LED by using 100 ohm resistor
Combine relay with IC 4013
In the circuit above you have succeeded to turn off the lights with this series. So how do you combine it with a bigger load like a 220V lamp
To make it you need several additional components
– 12 V relay
– a npn transistor. Read What Is a Transistor?
– a resistor
– a diode
So this circuit will turn on/off a relay then the relay will turn on/off the 220V lamp
A transistor is used to amplify an electric current before entering the relay. Meanwhile a diode is used as a snubber circuit
Thank you, I hope the explanation above about cmos 4013 toggle switch circuit is useful for you
