It shows the components of the circuit as simplified shapes and the facility and signal associates between the devices.
The main purpose of the two way switching circuit is to allow the devices to be switched on off independently of any switch no matter the current state of the switch.
This is the first method to make a 2 way switching connection this is the old method. Basic 2 way circuit power coming in at switch. So now that you have a basic concept of wiring a 2 way switch let s look at the following 2 way switch diagrams to see which type of circuit scenario you have. It shows the components of the circuit as simplified shapes and the facility and signal associates between the devices.
