This switch is designed to momentarily disconnect power to the vehicle's on-board power supply. It is mounted directly on the battery terminal and opens the ground circuit by simply lifting the flag. There is no automation, only good old mechanics, so the risk of something going wrong is practically zero. This disconnector is designed for current up to 750 amperes and voltage 12/24 volts, which allows you to use it on trucks, watercraft and cars. The housing is made of durable metal and is reliably protected against corrosion. The handle allows you to quickly disconnect or connect the power supply at the right moment even on a running vehicle without the risk of electric shock.
