Similar to a traditional power switch that is pushed up to turn on and down to go off, rocker switches operate like an "off/on" switch with a major exception — they rock back and forth to turn power off and on when pressed.

Rocker switch manufacturers design these switches for use in commonplace items like surge protectors, to control power in office machinery and even on airplanes and ships to turn various devices off and on. When looking to buy rocker switches online, ask yourself the following three questions:

1. What size, shape or color are you looking for in a rocker switch?

2. Do you require low-voltage rocker switches or industrial rocker switches?

3. Do you need to purchase illuminated rocker switches?

Determine what details appeal to you in a rocker switch

Rocker switches come in various shapes, sizes and colors. There are mini-rockers, full-sized rockers, round rockers and even sealed rocker switches suited for marine, transportation and agricultural industries where exposure to the elements is common. Today's rockers can even be purchased labeled or unlabeled.

I recommend: Westside Wholesale's inventory focuses on standard sizes, but comes in black and white and is sold single pole up to four-way. Maniktala Electronic & Engineering carries a variety of rocker switch types and shapes.

Choose between industrial rocker switches or those that are low-voltage

Industrial rocker switches are designed to handle higher amp and voltage ratings. Low-voltage rocker switches are ideal for residential and commercial lighting or devices where the power source wattage will remain low.

I recommend: Hardware and Tools carries an industrial rocker switch that can support a power range between 10 amp 277 volts and 20 amp 125 volts. Check out 1000bulbs for a low-voltage rocker switch with a dimmer ideal for low-level lighting that is designed for up to 450 watts.

Decide if your rocker switch requires illumination

Many rocker switches are sold with illuminating capacities. When they light up depends on how they are hooked up to the power supply. A rocker switch with independent circuitry can have a light activated on the switch face if it is in the off or on position, allowing it to easily be seen in the dark. With dependent circuitry, the light can only be seen when the switch is on.

I recommend: Discount Marine Supplies offers several black or white lighted rocker switches, in addition to some other choices in regard to illumination timing. They are all manufactured by Seachoice. Aircraft Spruce and Specialty's illuminated switches come in a variety of colors.

Helpful advice for making the most of this Guide

• •  Some companies can customize the rocker switch actuary (the plastic part that the person presses to turn off and on) to complement the area where the rocker switch will be housed. For instance, if rocker switches will be installed for power in a commercial office building with a modern look, you can design the actuary to reflect the building's style.
