An AUX BATTERY label and a battery icon with plus and minus markings make this push switch for Toyota auxiliary battery easy to recognize beside other accessory controls. The illuminated Large Push button provides a labeled control point for a compatible auxiliary-battery system.
Auxiliary Battery Symbol: design and use
Treat this product as a low-current control switch, not as a battery isolator, charging controller or high-current disconnect. A qualified installer must match it to the auxiliary system’s approved control input and a suitably fused relay arrangement. Battery charging, combining and load isolation require their own correctly rated equipment; the face label does not provide those functions.

Wiring and installation — fused relay required
Every installation requires a fused relay. This 3A, 12V switch must not carry the accessory load directly.

Relay, wire and fuse ratings must suit the accessory load. The supplied cable and connector connect the switch; additional power wiring is required for the equipment.
