Relay FAQ's

Normally open or normally closed, SPST or SPDT, resistor or diode: the answers from the people who make them.

How does a relay work?

A relay is an electromagnetic device, within which an electro magnet is fixtured to cause controlled movement either by magnetic attraction or magnetic repulsion. Other hardware attached to the moving magnetic portion of the motor such as relay contacts will cause switching of electrical circuits.

What is the difference between a SPDT and SPST Automotive Relays?

SPDT Relay: (Single Pole Double Throw Relay) an electromagnetic switch, consists of a coil (terminals 85 & 86), 1 common terminal (30), 1 normally closed terminal (87a) and one normally open terminal (87).

SPST Relay: (Single Pole Single Throw Relay) an electromagnetic switch, consist of a coil (terminals 85 & 86), 1 common terminal (30) and one normally open terminal (87). It does not have a normally closed terminal like the SPDT relay, but may be used in place of SPDT relays, in most places where only one thing needs to be switched.

Why do I want to use a relay and do I really need to?

Anytime you want to switch a device which draws more current than is provided by an output of a switch or component you will need to use a relay. The coil of a SPDT or a SPST relay that we most commonly use draws very little current and the amount of current that you can pass through a relay common, normally closed, and normally open contacts will handle up to 40 amps. This allows you to switch devices such as headlights, parking lights, horns, etc., with low amperage outputs such as those found on keyless entry and alarm systems, and other components.

Restoring a vintage ride?

If you are a vintage car or truck enthusiast, you know how difficult it can be to get your hands on the original OEM automotive relays that came in that beautiful vintage ride you've been restoring. Through our numerous years of experience and manufacturing in the OEM relay industry, we have acquired a variety of valuable contacts that can often times supply those parts.

About Relays R Us

The vision for Relays R Us came about over 40 years ago when the founder, Keith Pokorny, noticed there was something missing from the industry he had been involved in for so long: a smaller company that specialized specifically in OEM relays, and had the ability to both manufacture the product on a large scale, and sell them on a smaller level as well.
