Product Details

The WirthCo Battery Doctor Mini Master Rotary Disconnect Switch provides reliable battery power management for automotive, marine, and recreational vehicle applications. This heavy-duty disconnect switch allows you to quickly isolate your battery from electrical system drain when the vehicle is stored or not in use, helping prevent dead batteries and extending battery life.

Key Features:

  • 300-amp continuous duty rating for high-current applications
  • 2-position rotary dial with clearly marked on/off positions
  • Easy-to-grip control knob for simple operation
  • Protective bottom cover included to shield connections
  • Four mounting holes for secure installation
  • Designed for single 12-volt battery systems
  • Heavy-duty construction with corrosion-resistant materials

This disconnect switch is ideal for preventing parasitic drain on vehicles, boats, RVs, and equipment during storage. The compact design fits in tight spaces while the rotary dial provides positive on/off switching. The included bottom cover protects terminals from accidental shorts and environmental exposure. Installation is straightforward using the four mounting holes, and the switch can be mounted in multiple orientations to fit your application.

Quick and easy

Quick & easy! Great pricing!!

Ordered the ARB 50QT fridge from Autoplicity b/c they had every merchant beat by more than $100. Very happy with the transaction and would highly recommend - best prices bare none. I called Auto Anything and was told they match pricing with most vendors - except Autoplicity. I can see why. My first order but not my last!

Best price I've seen online and the shipping is extremely fast. I would definitely use this site again for future automobile needs.

good so far. received item on time, maybe even a little faster than I expected. the item was exactly as described, quality is good and exactly what I needed. it has been installed and works great. will do business with Autoplicity again. would definitely

Great thanks !!!

Ordered a Trac-Bar from Autoplicity, and didn't have any problems. WILL be back!

Very easy site to use...lots of inventory in stock...helpful staff! Would definitely do business again! By the way, lowest price anywhere!

Best Prices all around

So far autoplicity has been a great shopping experience.

They had all the parts that i needed and shipped very fast had them in two days after ordered will buy again from autoplicity.
