Buying Guide: Switches

Factors to Consider
Because switches are designed to meet the varying needs of different types of light fixtures and electrical devices, it’s important to keep these factors in mind:

Styles – Single-pole, Three-Way, Multi-location, Double Switch
Switch Ratings and Wire Compatibility – Residential (15 amp), Industrial (20 amp)

Light Switch Styles
While light switches may look similar, they actually come in a wide variety of types and styles. The one you choose will depend largely on:

Where it will be installed
Whether you want to be able to control a fixture from one or more locations
Personal preferences

You’ll also want to make sure you select a light switch that is compatible with the circuit where it will be installed. For example, if a light is controlled by one switch, you’ll need to replace it with a single-pole switch. Consult the listing below to learn more about the various types of light switches, their benefits and features.


Single-Pole
Controls one fixture from a single location Most common type of switch Easiest to install or replace Choose from classic toggle or rocker styles


3-Way
Controls one fixture from two locations Often used in stairways, hallways and large room Slightly more complicated installation


4-Way
Controls light(s) from three locationsone fixture from two locations Most commonly used in large rooms One 4-way switch must be used with two 3-way switches in a 4-way circuit Slightly more complicated installation


Multi-location
Controls one fixture from three or more locations Used in larger spaces where having multiple controls adds convenience and safety Slightly more complicated installation


Double Switch
Controls two fixtures without installing a separate box Installing two parallel switches with a double box also works Make sure there is plenty of room for all the wires so that it meets building code requirements


Dimmers
Allows you to adjust light levels in any room Available in single-pole, 3-way and multi-location versions Saves energy and extends bulb life

Switch Ratings & Wire Compatibility
Before you replace or install a light switch, it’s important to make sure the new switch matches the amperage rating and voltage of where it’s being installed.

For standard residential switches:
Amperage(amp) rating of 15

15 amp switches should be connected to a 14-gauge wire, which is found in most homes

For commercial or industrial switches:

Voltage (V) rating of 120

20 amp switches should be connected to a 12-gauge wire

V rating of 240
