A common use - would be to use one printer with four computers. Each computer has a data cable leading to the 4-way switch - and the switch has one data cable leading to the printer. Each user turns the switch to the relevant position in order to use the printer.

Can a 4 way switch be used in place of a 3 way switch?

No, a 4-way switch cannot be directly substituted for a 3-way switch. A 4-way switch is used in conjunction with two 3-way switches to control a single light or set of lights from multiple locations.

Why are your blinkers not working on your 1992 cadillac deville but your 4 ways are?

It's a different flasher unit and has it's own 12 volt supply fuse. Check the fuse first. After the flasher unit and fuse, the only other things it can be are the stalk switch or the wiring. The blinkers and 4 ways use the same wiring from the 4 way switch onward. A working four way flasher is a good indication that all the wiring from the 4 way switch is good.


How is one light controlled by three switches?

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.

Can a 4-way switch be used like a single pole switch. if so how is it wired?

Are you sure. They no longer produce a single pole switch in the color needed and we thought that a 4 - way could be sub'd. There is no reason that it would not work, electrically. The problem may be that it doesn't meet electrical code. If you use two terminals on the same side of the switch as you would with single pole, it should work.


What does a 4 way switch do?

Can you wire a four way switch with two pairs of two wire?

No, a four-way switch requires three or more switches to control a single light fixture from multiple locations. Each switch in the circuit needs to have three wires - one hot wire, one traveler wire going to the next switch, and one traveler wire coming from the previous switch. Using two pairs of two-wire cables will not provide the necessary connections for a four-way switch setup.
