2 Gang Switch Connection
Hi in my kitchen i am going to install a 2 gang 1 way switch to control main light and under wall units lights seperatly.
2 gang switch connection. If it has two switch buttons on it then its a double or 2 gang switch. Two way switch can be operated from any of the switch independently means whatever be the position of other switchonoff you can control the light with other switch. However if you need two switches to control a single lighting circuit such as in the case of at the head and foot of stairs so you can switch the lights on and off in both places you need to understand a 2 way switch. The electrical boxes are made of either pvc or steel.
The green screw on the 2 way switch is for the ground so all ground wires should be connected as seen below. This makes for a safe protected circuit by having all grounds intact. A 1 gang switch will control a single lighting circuit and with a 2 gang switch you can control two lighting circuits and so on. The steel boxes have the advantage of being self grounding and do not require a grounding wire.
So what have we accomplished. A 2 way switching connection means you can control an electrical equipment like bulb by two switches placed at different places generally used in the staircase. The black wires running to the two separate light fixtures are each connected to one of the switches. If your light switch has one switch button on it then its a single or 1 gang switch.
Wiring two switches in one box in this arrangement 2 switches are installed in one box. Two gang electrical boxes are electrical boxes that allow you to fit two outlets or two light switches in them.
