FREQUENTLY ASKED QUESTIONS
Answers to Popular questions

Why buy a fuse & relay panel?

When rebuilding, restoring, or refurbishing your vehicle, you’re bound to need electric pumps, fans, spotlights and more. These high-current devices will damage regular ignition key switches or low-current switch panels — however, an electromagnetic switching relay panel will give you the safe and reliable control you need.

Can this relay box operate “normally closed” devices?

No. Our SPST relay boxes are designed for standard normally open (N.O.) loads only. However, our specialty SPDT Bosch style relay boxes can power devices that are normally closed.
