Perko - Manual Medium Duty Master Battery Switches

SKU: WPMMDBS


Medium-Duty On/Off Battery Disconnect and Selector Switches

Ignition-protected switches for use with 6-volt, 12-volt, 24-volt, and 32-volt marine systems. Both 2-Position (single circuit On/Off) and 4-Position (dual circuit selector) models are available with or without Alternate Field Disconnect (AFD). When used with Non-Unitized Alternators, these switches will interrupt the field current (reducing the possibility of damage) if turned "OFF" with the engine running. The AFD-enabled models allow selection of any position including "off", without damage to alternator or electrical system.

Marine UL Listed - CE Certified

Made in USA.
