SPDT: When You Need to Switch Between Two Paths
SPDT stands for Single Pole Double Throw. This configuration gives you two output terminals and lets you choose how to wire them.Â
One output is normally open, and the other is normally closed. Depending on your system, you can wire the switch for either function. SPST switches only support one of those, so you would need a different part for each version. SPDT simplifies that by giving you both options in one switch and reduces the chance of ordering the wrong version.Â
