Finding electrical switch suppliers is not difficult. Even a quick shot on a general search engine yields many quality finds. However, general search engines do not know your specific applications and needs. When you begin looking at electric switch distributors there are some ways to weed out the good from the bad.

Here are several simple tactics for finding the best electrical switch distributors for your needs:

1. Search out companies that sell the brands you've already used and trust.

2. If you have the knowledge to tell the difference between low and high quality components, or if you know exactly what you're looking for, wholesale and cut rate websites can save you some money.

3. If you need rare switches, shop sources that specialize in your particular range of electrical switch applications. You may find serviceable parts elsewhere, but the application-specific websites will carry a larger selection of your parts and may also have helpful information.

4. Look for electronic switch distributors that have large selections and quality website designs. These types of websites more often have quick shipping, the best customer service and give you the most product options.

Find sources of wholesale switches

If you know what you want, then why pay more? There are many electrical switch sources that sell high volume and specialize in keeping their prices low. The drawback is that these websites usually do not have as much product information. One way to get the best of both worlds is to find the product you want on the websites of electrical switch manufacturers or retail sources and then find the same parts on wholesale sites.

I recommend: For a good electric switch price, try Westside Wholesale, Inc.. They promise fast delivery and have very cheap prices on basic wall toggle and rocker switches. For a wider selection, however, Fox Electric Supply Company is a great choice.

Shop websites that have large selections of electrical switches

If you're looking for a very specific type of electrical switch, then the main point is finding a quality distributor that carries it. However, generally speaking, the websites with the largest selections will give you the most options. You may even find something you hadn't thought of previously.

I recommend: For an almost exhaustive list of industrial switches, organized by type, check out Grainger. They have a search tool to help you narrow down your choices. If you want to buy electrical switch parts for your home, business, or industry, then Leviton is a good choice. They carry AC switches at each grade.

Locate electrical switch providers that specialize in your field

Electrical switch distribution is broad. There are many varieties of the industrial electrical switch, and then there are standard varieties of domestic and commercial wall switches. Maybe you're looking for an electrical transfer switch, or a bat handle toggle switch, common electrical supply switches, or perhaps you need something much more specialized. The more particular your need, the more advantageous it is to find a specialty source.

I recommend: Nexus specializes in telephone and microphone switches, such as push button and push-pull electrical switches. Another place to look is Apem Group. The company does not necessarily specialize as much as they just flat out carry a wide variety of unique and hard to find electrical switches.

Electrical switches are controls consisting of an electronic device for making, breaking or changing the connections in a circuit. Switches allow electric current to flow when closed and prevent the current flow when opened. A simple switch has two pieces of metal called contacts, which touch to make a circuit and separate to break the circuit. There are several key terms that you should know. This guide covers some of the types of electrical switches, such as rocker switches, rotary switches, dip switches and toggle switches.

Toggle switch

A toggle switch uses a lever, protruding from the front, to open or close the circuit. The toggle switch design makes it easy to tell whether the switch is on or off.

I recommend: Visit All About Circuits for technical information about toggle switches.

Rocker switch

A rocker switch has a pivot and an actuator that moves like a playground see-saw. You push one side down and the other side goes up; push the up side down and the other side goes up.

I recommend: Global Spec has detailed information about rocker switches.

Transfer switches

Transfer switches transfer electrical power back and forth between two power systems. You will find transfer switches in applications that require switching between two power sources.

I recommend: Lazar Rozenblat gives detailed information about transfer switches and their application.

Rotary switch

A rotary switch has two or more different states or modes of operation. It operates by rotating a control knob (attached to its shaft) clockwise, counterclockwise or both.

I recommend: All About Electronics has information about rotary switches.

Relay switches

Relay switches are electrical switches that open and close under the control of another electrical circuit. In the original form, an electromagnet operates the switch to open or close one or many sets of contacts.

I recommend: The Electronics Club publishes detailed information about relay switches and their applications.

Dip switch

A dip switch is a set of manual electric switches that are packaged in a cluster in a standard dual in-line package (Dip). Dip switches are ideal for applications in telecommunications and networking.

I recommend: For information on dip switches, visit 10 Stripe.

Slide switches

Slide switches have a distinguished method of activation. The switch is a slider that slides from position to position. You can either lower or raise the handle depending on the type of actuator.

I recommend: Browse through Apem Components for information about slide switches.

Electrical switches can make, break or change connections in a circuit, and the types of switches available for home, commercial, industrial, motor and electronics uses vary widely.
