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

**Title: Perfect Fit and Style for the Price!**
Size: XX-Large, Color: Navy Blue
I recently purchased the Gafeng Men's Trench Coat in XXL, and I couldn't be happier with my choice! At 6'2" and 210 lbs with an athletic build, I was initially concerned about finding the right fit, but this coat exceeded my expectations. The fit is perfect—tailored yet comfortable—and the length is just right. The style matches the pictures exactly, which is something I’ve struggled with in past purchases. The lightweight, wooly fabric is surprisingly warm, making it ideal for winter without feeling bulky. For the cost, this coat is a fantastic deal. It looks sharp enough for business attire while still being versatile for casual outings. Highly recommend for anyone looking for a stylish and functional overcoat!

Definitely NOT the COLOR that’s advertised but not bad
I got this for my son for him to have his 1st official “dressy” coat for certain occasions. It will do for the price, but as I said in the description, it’s definitely not the color that’s shown in the advertisement. Its also not taken in like the picture. But not bad. It’s more of a camel color than a khaki like the advertisement. My son is 5’9 and has a slim build, I bought a L because he’s tall and this fits fine to be honest. I want him to be able to grow into it next year as well. If you have long arms you may wanna size up.
