The M-284 Series 36 V 175 A Marine Battery Disconnect Switch is a marine-grade, brass-body
master battery disconnect switch for boat and commercial vehicle applications that features
single-pole, single-throw (SPST) circuitry.
Disconnecting a boat or vehicle battery from the electrical system with a master battery
disconnect switch prevents potential thermal events and ensures the system is shut down during
maintenance or an emergency. In addition, using a manual battery disconnect switch during
periods of inactivity, such as when a boat or vehicle is stored, prevents parasitic loads from
draining the battery.
This Cole Hersee brand disconnect switch is available in a variety of configurations,
including UL Listed models and sealed models.
