Is double pole the same as 2 way?

Double pole light switches, also known as a four-way switch, are two single pole switches put together. Two separate circuits are controlled by one switch. This is typically used to control a circuit from multiple locations in a series of three switches on one circuit.

Do I need 20 amp switches?

So, basically the switch needs to be a 20 amp switch for multiple receptacles on a 20 amp circuit. In theory it’s fine as long as the combined draw of the 3 receptacles never goes above 15amps.

Should I use single or double pole sockets?

Whilst a single pole socket is generally cheaper it is always preferred that customers/electricians install double pole sockets for safer isolation of the plugged in appliances.

Can I use a 2 way light switch as a 1 way?

Yes, a two way switch can easily operate as a one way. A two way switch is, at least in all the cases I know of, identical to a one way switch, except that it has two sets of contacts and a common. Simply omit wiring the second contact, and, of course, omit the second switch.

Can you use a 2 way switch for 3-way?

Yes it can work. 3-way switches are spdt (single pole double throw) with 3 screw terminals, and regular switches are spst (single pole single throw) with 2 screw terminals. Just pick the correct two contacts and you are good to go. . … A multimeter is the quick way to figure out which terminals to use.

Do I need a double pole switch?
