Battery Disconnect Switches
Stop battery drain and prevent the theft or unauthorized use of equipment by disconnecting batteries when not in use.
Knob and key actuators can be removed to limit access to the switch.
Use remote-mount switches for easier access. Run a battery cable from the battery to the switch.
Switches with a fused bypass maintain a trickle of current to accessories, such as radios and computers.
Switches with a wing nut accommodate lug terminals.
