How many terminals are there in a four way switch?
There are four terminals that provide two sets of toggle positions on a four-way switch. Each set of terminals is one of the toggle positions. When the switch is in the up position, the current can flow through two terminals. In the down position, the current flows through the other two terminals. Many times, four-way switches will come ...
How to tell which terminals go together?
To find out which terminals go together, you can use an ohm meter to test the terminals and the toggle positions, or take a quick look at the manufacturer's instructions, which should outline the pairings. Each set of terminals will connect to the traveler wires from each of the three-way switches. When connected properly, you'll be able to turn lights on from either of the three-way switches or the four-way switch. In the event that you need to switch lighting from more than three locations, simply add additional four-way switches between the two three-way switches.

What brand 4 way switch do you guys have? I remember in the 80s fixing and adding pickups to a friends Japan Tele and what a mess! I knew the Strat schematic by heart, but not the Tele, so when I went to put in the USA switch using the schematic I made from the way it looked when I opened up the cavity nothing worked.

I installed my 4 way last night using the Callaham switch and tip following the schematic from the Klein pickups site.
How to check continuity on a 4 way switch?
Pick one of the four posts of the 4-way switch to hook up the source power. Put one lead of the multimeter on this post . Test the other posts to see which one has continuity and which does not. Leave the lead on a post that does not have continuity with your initial post. Now flip the switch. Does it have continuity now? All you have to do is use two posts of your 4-way switch that alternate continuity when you flip the switch. That's all a regular switch is doing, breaking the continuity between your source power and your load.

Attach the black and white/blue traveler wires entering the 4-way switch box to the "in" terminals, often the top terminals on the 4-way switch - black on the left top pole and white/blue on the right top pole. Some 4-way switches may have the "in" and "out" pairs opposite each other, rather than top and bottom.
What color wire to use for a 3 way switch?

There will also be a "grounding" terminal on the switch, which is connected to the bare grounding wires (or to a metallic junction box, if you have one) for additional safety. 4.
How many poles are in a 4 way switch?
A 4-way switch has 4 terminals or poles. Two terminal/poles are labeled "in," and two are labeled "out.". Pairs of wires, called "travelers," will connect to each side. When the switch is operated, current will either travel straight through or crisscross.
How are two 3 way switches connected?
Two 3-way switches are connected to each other via "traveler" wires, only one of which is "hot" in any given switch setting combination. The 4-way switch connects in the "middle" of the two travelers. Each 3-way switch has a "common" terminal and two traveler terminals.
What is the red wire on a light switch?

What is 14-2 wire?
In the picture given above, a 14-2 cable (2 wires with the ground) is being used and it is running from the light fixtures to the three-way switch. A Three-wire cable with the ground (or 14-3 cable) is employed to take power to the 4 way switch and another 14-3 cable is used for connecting the last 3-way switch where the circuit ends.
What color wire goes to the brass screws?

Why are switches spring loaded?
Switches are spring loaded to minimize arching and prolong their life. However, a very small amount of arcing is present when a switch is toggled. A bad switch may not fail completely, burned contacts may cause intermittent failure. Keep this in mind when troubleshooting switches.
What is the black terminal on a toggle?
When the toggle is in the other position, the left side black terminal connects to the right side brass terminal. The right side black terminal connects to the left side brass terminal. Actual toggle position can vary with make and model.
What happens when a 3 way switch fails?
Usually when a 3-way or 4-way switch fails, lights can be toggled on and off on all but one switch. Any switch that toggles the light (s) on and off is probably working properly. Follow these steps to find which 3 or 4-way switch is bad.
Do you have to remove the wires from a toggle?
The wire connections do not have to be removed. Using a continuity tester, check continuity between terminals as shown. Actual toggle position can vary with make and model. With the toggle in one position, you should get continuity on the same side.
Is a switch a good switch?
If it does, it is a good switch. Leave the light on. Repeat the process for the rest of the switches. One of these switches will not turn the light on and off (while the light is on) and that is the bad switch. Switches are spring loaded to minimize arching and prolong their life.
