A battery switch is the first device you interact with when turning on a system and the last device you turn off when you end the day. Having a battery switch you can trust prevents parasitic draw on your battery bank when you are away. These 300A battery switches are small but mighty. The studs are swedged using a 1 ton press into the copper bus inside the switch. That ensures that the battery lug you connect to the stud provides virtually resistance free connection through the switch.
