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 50 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

Good scent and sizable soap bar
I bought the 6-pack for everyday use and really like the fresh, clean scents — nothing overpowering. These bars lather nicely and rinse off without leaving a greasy film. Gentle enough to use on my face, body, and hands without irritation. Each 5.3 oz bar lasts a good while — better than many other “gentle” soaps I’ve tried. Packaging arrived neat and intact, perfect for gifting or sharing. Great value for the set and the scent variety keeps shower time pleasant.

Solid Soap Set for Men
This natural men’s bar soap set has quickly become a daily favorite after a few uses. The fresh, clean scents are subtle and not overpowering, giving a nice masculine smell without lingering too strong. Bars lathers easily and feels gentle on the skin, making it great for face, body, and hands with no dryness afterward. The bars are generously sized and seem to last a long time.

Keeps the bees and bugs out of beverages
Great . I have used on several different brands of drinks and they work nice to cover your drink once opened. They don’t prevent the spills but reduce the spill !! And the slide into your shirt or jeans pocket great!
