Features & Benefits
Isolates the batteries and eliminates battery drain when vehicle is stored overnight or for longer periods. Electrically cuts off battery
power for safety or when the vehicle is being serviced.

Available with integral holes to accept lockout/tagout. No need to purchase additional hardware.
Plastic construction will not corrode and stands up to roadsplash and salt spray. Ingress protected to IP67/IP69K. Switch can be
mounted anywhere on the vehicle.
Units have a depth of only 3” (knob front to end of studs) – can be installed in locations where behind-panel space is limited.
Stainless steel hardware and tin-plated copper contacts minimize resistance in harsh environments.
