SPDT RELAY WIRING DIAGRAM MULTIPLE

Wiring Diagrams - Relay Pros
This page demonstrates several simple ways to wire a relay for various applications. Diagrams will show how multiple relays, one relay or another or just one relay can control your device. All examples shown are for SPDT (single Pole Double Throw) relays which includes any
Single Pole Double Throw (SPDT), Single Pole Single Throw
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) 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.
Special Applications with SPDT Relays
Using a 30 amp SPDT relay, One Channel to Multiple Outputs: Only one output can be active at anytime, the one first in the chain (bottom relay in diagram) will have priority, so if you wanted to have the ignition from the key to have priority over the ignition from the remote start
