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

Nice product
Color: 2-Speed Rechargeable Set with Charging Base
Edit: Customer service actually did offer to replace it. Received the new set and it works fine. Nice set. Only gripe is I think that the motor could be a little stronger. Sounds like it’s struggling at times. Received a defective item reached out to customer support for Circle joy and they’re basically saying that it’s user error and not a defect in their product, even though I explained to them that the other one works fine. When adjusting the coarseness on one of the grinders, the grinder ends up loosening up, which ends up with you spilling the pepper corns everywhere. It’s a nice set if it worked right but for $40 I expect her device to be a little more polished.

great for my bad hands, hygenic, easy to use.
Color: 2-Speed Rechargeable Set with Charging Base
so far so good. I cook a couple times a day. I also have bad RA in my joints. this product has really helped already. from the clean size adjustment to the ease of charging. Like i have owned it for years is how easy this product has entered my kitchen routine. strong product and hygenic because you adjust the grind from twisting the body, not messing inside the grinder.

Good looker but terrible performance
Color: 2-Speed Rechargeable Set with Charging Base
I purchased the product and the base would not attach from the charging module. This is their big selling point. I requested a replacement and sadly the replacement was of the same batch run as the original soo…. Yeah that base would not detach. There are videos showing how easy it is to detach base from charging module. Not theses units. Circle Joy customer service is an @gmail.com. They said base is not designed to be removed frequently. I reminded them the separation feature is their highlighted feature. I was just looking for a base. Circle Joy said no…. If I do not like either unit just return them to Amazon.???? In the meantime, after maybe a dozen grinds, the original unit quit grinding normally and would barely grind at all. I shook it out and it worked again but doesn’t sound right. Two takeaways: 1) Poor product quality. 2) I am sooo done with trying to work with Amazon on replacement items. Save yourself a tone of aggravation and just return the order and reorder if you dare. Otherwise good looking and heavy feel and works great about 10 times. Too bad so sad. Now I have this huge return hassle with Amazon.
