Status Diagram

Battery switches or contactors disconnect 12-volt loads from individual circuits connected to the chassis battery. What makes ours special is the logic circuitry that accommodates different voltage cut-offs via toggled dip switches. Additionally, an alarm or LED signal can be tied into the switch as a low voltage warning. The switch can be bypassed and shut off by disconnecting the ground. Our contactors are made of the highest quality anodized aluminum with copper and tin-plated connectors and stainless steel locking nuts. It is solid state with no moving parts and carries a two-year advance replacement warranty.
