What are the three terminals on a toggle switch?
Terminal 1 is connected to one load or accessory, Terminal 3 is connected to another load or accessory. Terminal 2 is connected to power.
Do you need to ground a toggle switch?
Grounding light switches have become commonplace, used as a preventative safety measure. It is perfectly legal to wire a light switch without the inclusion of a ground. Dimmers will require a ground wire but traditional toggle-type switches will not. Omitting a ground wire on any switch is not recommended.
Which way is off on a toggle switch?
The power off (circle) symbol or “O” on a button or toggle, indicates that using that control will disconnect power to the device. The power on (1) symbol on a button or toggle, indicates that using that control will connect power to the device. Those are the numbers one and zero. The rules are that zero means off.
Why do some switches have 3 prongs?
Pin 3 is where the switch is either connected to ground or left open. This is the pin where the rocker switch receives its voltage. This is the pin that connects to the load of the circuit, whatever the rocker switch turns on when it's switched on. Ex: lights, motor, etc.
Is the dot on a switch on or off?
IEC 60417-5007, the power-on symbol (line), appearing on a button or one end of a toggle switch indicates that the control places the equipment into a fully powered state. ... IEC 60417-5008, the power-off symbol (circle) on a button or toggle, indicates that using the control will disconnect power to the device.
How can I tell which wire is common on a 3-way switch?
The switch wiring for three-ways is normally Red, Black, and White. If the White is correctly used for neutral, the connected switching wires are Red and Black. The White (neutral) is often referred to as Common, but the colored wires are both used as Hot wires, alternately as the possible switch positions are made.
What color wire goes to the black screw on a 3-way switch?
The black screw has the black (common) wire that runs up to the light through the yellow cable. The two grounds are connected together and then to the green ground screw on the switch. To summarize, the black screw gets either the wire from the electrical panel or the wire going to the light.
