Why would one light switch show only 60V while all other switches in the circuit are showing 120V?

Good question, I have 3 in a circut, 2 at 120V, and one at 14V. Already replaced the outlet thinking that was bad, same result. More than likely there are defective connections somewhere in the wiring. Possibly under a wire nut. It could be all or none of the above. All depends where you put your volt meter to do the reading. With the light switch in the off position when you measure across the switch you will get line voltage of 120 volt, but when you turn on the light, it will read the voltage drop of the switch, should be 0 volts unless the connection is bad or if it is a dimmer switch then the voltage will be all over the place. from: bmetong

A switch in a circuit will quickly allow you to break the circuit, without changing the wiring. For example, a light switch. By turning a light switch off, you are breaking the circuit and, thus, turning the light off.

That is called a 4 way light switch circuit. On each end of the circuit you install a 3way switch and in the middle you install a 4 way switch.Answer using British TerminologyIn the UK, 'three-way' switches are called 'two-way' switches (more logical, if you think about it!), and the 'four-way' switch is called an 'intermediate' switch.

Send power to the 1st switch and then send the power from that switch when it is in the on position to the second switch. Then send power to the light from the second switch. That way both switches will have to be in the on position for the light to be on.

That is called 4 way intermediate switch wiring. Click the link to watch a video I have posted showing how to wire just such a circuit.

There is a relay switch in the circuit which switches the light on & off when you activate the turn signal.
