SPST vs SPDT Relays. What’s the difference? Single Pole, Single Throw (SPST): This relay will be identified as having a middle 87b spade (or no middle spade at all).This is the most common relay used for fog lights or other simple circuits.. Automotive SPDT Relay and Harness - What are they and how do I use them Relay (SPDT - Single Pole Double Throw) - Is an electromagnetically device which has a energize able coil. Relays are used in a wide variety of applications within automobiles.. 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 all diagrams shown on this site where terminal 87a is not used..

Latching relay manufacturers, Latching SPDT 30,40 Amp, and other specialty relays.. mon on alarm systems) to 85 (or 86),and 12-volt CONSTANT to the other pin (86 or 85). Basically,it doesn’t matter whether pin 85 or 86 is used for ground or 12 volt if the relay does. This document describes how to wire a relay into a motorcycle's 12 volt electrical system in order to power add-on accessories such as radar detectors, GPS'es,.

This correlates to the following in the relay: Terminal Descriptions. COIL- This is one end of the coil. COIL- This is the other end of the coil.These are the terminals where you apply voltage to in order to give power to the coils (which then will close the switch)..
