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

Excellent Product!!! Will purchase again!
Size: 2' x 3' (Natural), Color: Wolf Tipped
Instead of ordering a cover for reclining loveseats, I chose to drape one of these over the headrest on either end of our loveseat. Not only do they protect the leather, they also help to elevate our decor. The rugs were received in a very timely manner. They are super soft, & warming as we move into the winter months. We've had family & friends comment on how great they look. 2 of them have already ordered, & added them to their sofa/loveseat/recliner decor. Have an issue of them slipping, add some velcro in between the crook of the cushion & the back of the furniture piece. It doesn't show & will help to keep the rug in place; if your busy body.!

Perfect for sensory sensitive kids and for the pure beauty of it

After speaking over the phone with the seller, I was confident in this purchase for my SPD son. They do not use harsh chemicals or dyes in the process. It is from New Zealand and the only use in Vietnam is for shipping. My son hasn't been diagnosed yet for Autism but he is in the process. He is super sensitive to all things sensory and Amazon feedback isn't the place to give specific details on his condition but I will write that when he fist touched it- which was willingly- he smiled and asked to sleep on it. When he laid down on it and I covered him- he was calm and smiling. In the pic I provided he is calm and holding his door (his obsession is doors and windows). He even set his door down to hold the fur. For other mommies and papas with spd/autistic kids you know that willingly touching a new fabric and setting down an obsessive item is huge and super encouraging! I am so grateful to have such a quality item that is affordable for my special needs son. His older sister received one as well as is now pretending to be a sheep. Fun for everyone! The ONLY negative is that the brand/info sticker on the pelt was a pain to get off and pulled some of the felt - not damaging it but blemishing the unity -but if the skin is down it will not be noticeable. A super fun detail is that all of the fur is combed out but there were a few strands that were wavy and had a slight curl- I LOVED that. There was no odor at all which is great! I expected an animal smell which is better than chlorine or dioxin which is what competitors use in their process. There is no noticeable seam in the middle on the top where the two pelts are gathered. I am soooo satisfied!

Exactly as described and what I needed.
Size: 2' x 6' (Natural), Color: Wolf Tipped
I have a bad back along with other medical problems. I bought this for padding in my wheelchair. Very thick, soft, flexible, everything I needed. No smell and very little shedding even initially. Arrived quickly and well packaged.

Feels soft and looks great, just make sure to measure
Color: White+Black(Grey)
We ended up returning it because it was too tight to fit our console. Just make sure to measure yours. Still, 5 stars on quality.

Love it
Color: White+Black(Grey)
This is amazing. Thick and fluffy, but not so much that it would be in the way. Easy to install and now that surface is protected and comfy.
