Now place your switch to the location from where you want to control. Take the screwdriver and tied the switch onboard.
Wire a light switch with 3 wires
3-wire is also known as a 2-way switch. In a 2-way switching system, the user wants to control the power wire (black wire) to turn off and on. The normal switch has two terminals one is neutral which is directly connected to the light. And the other one is power (Black wire ). Electricity flow by this wire and the light on-off depends on it. The switch connects the two ends of the black wire. 2-way has 3 terminals which are called common, L1, and L2. Both normal switch and 2-way switch look the same from the front side but the inside is different. By normal switch, the user can control electricity flow from one location but by the 2-way switch, the user can control from two locations.
In a 2-way switching system com, L1, and L2 are three terminals. Now connect 1st switch L1 to 2nd switch L1 and 1st switch L2 to 2nd switch L2. Then connect the power wire to the 1st and 2nd switch.
