A The wiring of three-way switches is certainly more complicated than that of the more common single-pole switch
, but you can figure it out if you follow our diagrams.
If it works alone, it's a simple, single-pole switch. If you can operate the light from two locations, the switch (or switches, if you replace both of them) you'll need is a three-way switch.
Now that your brain and your tool belt are overflowing, let's start with the replacement of a single-pole switch. Make sure your circuit is dead, then remove the coverplate and switch retaining screws.
configurations with up to 12 throws are available, as well as SPDT and DPDT versions.
Simple, so-called single-pole switches
might have only three wires--two insulated wires that carry current and a ground wire, which is sometimes not insulated.

Rated at 16(6) A, the 250-VAC T125 single-pole switches
are available in non-illuminated or LED-illuminated versions with ENEC approval.
Although single-pole switches
might have been included in the instrument to open the circuits of three of the dry cells when the comparator is not in use, this was considered an unnecessary refinement.
Key features of the device include an onboard single-pole switched
capacitor filter that eliminates the requirement for external passive components to set the cut-off frequency, and a self-test allowing the verification of the mechanical and electrical integrity of the accelerometer at any time.
