What is a 1 way switch on a light switch?
1 Way Switches: If a light switch is ‘1 way’ this means it is just an on/off switch. This is the simplest type of switch that you can get. The single switch controls a single light (or lighting circuit).
How do I identify a L1/L2 switch?
Nearly all new switches are identified with "Com or L", "L1" and "L2". Your "A Com" Is "L" in bank 1, with "A1" and "A2" being "L1" and "L2" of bank 1 respectively. Then it repaeats for the other bank, "B Com" is "L" of bank 2, and "B1" and "B2" are "L1" and "L2", respectively.
How do I switch between B1 and B2 lights?
The 'Switched Live' to your lights is from B1 and A2. B Com = L (the other L!) B2 = L2. On the new switch Link the 'Ls' and feed the 'Live' to either of them.
What does AC only mean on a light switch?
AC Only This marking indicates the switch is designed only for alternating current wiring. This is not a marking you normally need to worry about since all standard household wiring is alternating current. This marking is usually on the front side of the metal strap.

Does it matter what wire goes where on a light switch?
In the case of a single-pole switch, these wires are interchangeable—it doesn't make any difference which wire is attached to which screw terminal. Inside the switch is a metal pathway that closes when the switch is in the ON position and opens to interrupt the flow of power when the switch is turned OFF.
What is A1 and A2 on light switch?
A1 or A2 WILL turn power off by toggling down. A1 and A2 will power on/off (like std. 2 pole switches but only if A1 toggle is up). A2 will NOT power on after A1 powers off (TOGGLE DOWN). A1 box has four wires; red, black, white, & neutral.
What does L1 L2 L3 mean on a light switch?
Two way switch Note that L1 and L2 are never connected together. Again, some makes of switch may have alternative markings such as L1 L2 and L3. This type of switch is used where two switches control one light, such as at the top and bottom of a stairway.
What is B2 on a switch?
B2 - Single Break, Subminiature Basic Switches The B2 series offers both commercial and military grades with a choice of two widths and a variety of terminal styles.
What is COM L1 and L2 on a light switch?
One way switch Typically, these terminals will be marked COM and L1, or sometimes L1 and L2. Either way, it does not matter which wire is connected where. Usually the permanemt live (from the supply) is connected to COM and the switched live (to the lamp) is connected to L1.
What wire is common on a light switch?
Black wire: This is a hot wire that carries electricity from the power source to the first switch in a typical 3-way setup. It's also called the “common wire” or the “line wire.” Unless the breaker is off, this black wire is always hot.
Which wire is L1 and L2?
The incoming circuit wires that provide the power are referred to as the line wires. L1 (line 1) is a red wire and L2 (line 2) is a black wire. Together, they show the motor voltage. Having both an L1 and L2 indicate that the motor voltage may be 240 volts.
What is L and N in switch?
There are two different name, L (Live) and N (Neutral) on the AC input terminal. Please refer to Fig. 1 for the wiring of the AC input.

If you have a dimmer switch they are described in the same way; a 1 gang dimmer switch will have a single dimmer on the plate, and a 2 gang dimmer switch will have 2 dimmers and so on. 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.

What is the difference between L1 and L2?
L1 and L2 are “line 1” and “line 2,” and “COM” is “common.”. Depending on the position of the switch, either L1 or L2 is connected to “common” —hence the name; it is the terminal that is “in common” between the two positions.
How many connections does a light switch have?
some light switches have 4 connections these are called intermediate light switches. these can be for turning the lighting circuits on & off from multiple locations for example a long corridor or stairways may have 5 lights installed and with it switch its possible to turn the lights on or off at each of the 5 locations.
How many switches can toggle a lamp?
If the second switch is connecting the lamp to the wire energized by the first switch, then the lamp is on. Either switch can toggle the state of the lamp. More than two switches add additional “four way” switches between the first two. A four way switch takes in two power wires, and sends two out.
How to control a light from two different locations?
This is known as a ‘3-way switch’ and is used when you want to control a light from two different locations. You need two of these switches. On the first switch COM is the hot leg (typically the black wire) , L1 connects to L1 on the second switch, and L2 goes to L2 on the second switch as well. The light connects to COM on the second switch and the other side of the light goes to neutral (typically the white wire). Now you can operate the light either on or off from either switch. Wiring is not for amateurs though so hire an electrician to be safe!
What is a 3 way switch?
Commonly called a 3-way switch and it is used for lighting circuits where more than one switch location is used to control the same lights. It may also be a selector switch, with L1 and L2 connected to two different supplies, such as regular power or emergency power, or constant power/timer. Tom Quetchenbach.
