Product Description

Medium Duty Battery Selector Switch w/Key Lock

Perko's 8501 Series battery selector switches are among the most popular battery switches ever produced. Their use of the traditional Perko bolt circle makes for easy installation, whether new or as a replacement. These switches can be mounted in numerous locations. And as ignition protected switches, they can be installed in the engine rooms of gasoline powered boats.

In addition to doing everything a battery disconnect switch does, battery selector switches permit battery selection (of two or more batteries) for specific purposes including starting engines, running accessories or even recharging. They allow for the use of one or more batteries in systems with one or more engines and facilitate putting batteries in parallel for emergency starting when one or both batteries are substantially discharged.

Perko battery switches are designed for surface mounting. Standard duty switches have a bright red polycarbonate housing for safety with a large easy-to-turn black knob. The housing of the heavy duty switches are red fiber-reinforced polycarbonate. Selector switches are designed with a "make before break" feature. This allows switching between the "1", the "ALL" and the "2" positions while the engine is running. Models with an "Alternator Field Disconnect" feature offer protection for Non-Unitized Alternators should the switch accidentally be turned to the "OFF" position with the engine running.

Versions of the 8501 Series switches offer additional features such as alternator disconnect and key lock security.

The 90° rotation feature allows users to feel the switches' position in no light situations and the classic shape of the knob makes it easy to turn.

High conductivity studs are long enough to handle more than 1 cable and strong enough for torque needed for secure connections. Optional spacer ring (PN 0462DP0RED) allows for the use of larger cables.

Specifications:

  • Diameter: 5-1/4"
  • Depth: 2-5/8"
  • For use with 6 to 32 Volt Marine Electrical Systems
  • Capacity - 250 AMPS Continuous, 360 AMPS Intermittent
  • When used with Non-Unitized Alternators, these models will interrupt the field current (reducing the possibility of damage) if turned "OFF" with the engine running

''Awesome discounts on fishing reels and GPSs. Plus they have next day shipping. The convenience of online shopping is awesome, especially since it's getting harder to get around in store.
They made sure I got the electronics I needed and all the hardware for the install. They even do repair and installs, so I ended up hiring them for the work I needed done on my Mercury. Awesome experience.''

"Great experience! I Was looking to purchase a head gaskets for my Johnson 150 hp outboard motor. Mike & Ashley researched parts I needed and come to find out they turned me on to my outboard engine used O-Rings to reassemble my head covers and provided me with parts and torque specs! Thanks! 100% positive feedback and Recommend this Family Business if you need Marine Supplies."

SCOTT

Family owned and operated, which is a huge plus for me! I was browsing the website looking at Garmin gps units, their prices are great and competitive! I reached out to them to ask where I might find a hard to find lower unit part I was needing. They had it in stock! If they don’t have something in stock, they will get it asap! 100% recommend and I will buy from them again in the future!
