Medium Duty Battery Selector Switch w/Key Lock

Perkos 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

Nice & comfortable
Size: XX-Large, Color: Grey Heather, Size: XX-Large, Color: Grey Heather
This is a nice & comfortable sweat shirt. I wear a 2X and this fits me comfortably. The stitching is right on as there are no loose threads anywhere on the shirt. This shirt is medium thickness & has a little bit of stretch to it, which is all one needs. From underwear to sweatshirts FOTL has does a great job once again. For the price paid you are getting a great value for your money.

Nice fit and warm, but bad material.
Size: 4X-Large, Color: Black
Not good material, now it looks like having four or five years of use and is not 1 year old.

Meets the demands.
Size: XX-Large, Color: Black Heather Pullover
Good quality and soft. Not to thick and breathable. Comfortable for all day use. Pilling is an issue inside after a few washes. Great value for a hoodie. Size is good but will shrink after a couple washes. Not to warm.

Excellent quality, thick, warm and comfortable!
Size: 3X-Large, Color: Duffle Bag Green
I bought this sweat shirt for my husband, and had to buy him another because I love it so much!! My children have tried to take it from me several times. It is so soft, super thick, and warm. I love the fit, it is a little baggie just how I like them. The quality is great for the money, at this price sweat shirts are usually see through and bad quality but NOT this one!!!!

A sweater is the ultimate clothing item for staying warm and cozy. Whether it's a chilly winter day or a cool summer evening, a sweater is there to provide comfort and protection. Its soft and knitted fabric feels gentle against the skin, making it a pleasure to wear. One of the greatest advantages of a sweater is its versatility. It can be dressed up or down, depending on the occasion. Pair it with jeans for a casual look, or wear it over a dress for a more elegant ensemble. With so many colors, patterns, and styles to choose from, there's a sweater for every taste and preference. Not only does a sweater keep you warm, but it also adds a touch of style to your outfit. From chunky cable-knit sweaters to sleek and form-fitting designs, there's a wide range of options to suit any fashion sense. Sweaters can be accessorized with scarves, hats, and jewelry to create a unique and personalized look. Another benefit of a sweater is its durability. Well-made sweaters are built to last, making them a wise investment in your wardrobe. With proper care, a sweater can withstand years of wear and still maintain its shape and quality. In addition to its practicality and style, a sweater also holds sentimental value. It can remind us of cherished memories, like cozy evenings by the fireplace or family gatherings during the holidays. Wearing a favorite sweater can evoke feelings of comfort, nostalgia, and a sense of belonging. In conclusion, a sweater is the optimal choice for both fashion and function.
