## Overview

Designed for tight spaces, it offers three mounting options and ignition protection for safe engine room installation. Its make-before-break contact design enables uninterrupted power transfer between battery banks, while the emergency combine feature ensures reliable power availability. Durable tin-plated copper terminals and a tactile switch face enhance usability and longevity, making it a top choice for professional marine electrical management.

## Description

This compact battery switch is designed to manage a single battery connected to a single load group and supports flexible installation in a variety of panel or engine room layouts. Its small footprint and three available mounting options make it suitable for areas with limited space. The switch includes ignition protection for use in gasoline powered engine compartments, allowing safe placement in locations that require protected components. The tactile surface of the switch face and the removable knob help support operation in low light conditions and contribute to preventing unintended power flow during electrical system service. Tin plated copper terminal studs are built as a single piece and provide sufficient length for connecting multiple cables while supporting secure fastening. With its combination of protective features, connection capacity, and adaptable mounting options, this switch offers a practical solution for managing basic battery control needs in marine electrical systems.

Review: Works perfectly for my application - This seems to be a high quality switch from a trusted brand. I use it to switch between two house batteries in my VW Westfalia Syncro Camper Van, or to combine both if needed. It also allows me to disconnect both batteries when needed, during wiring or electrical maintenance for example. I will say that it would have been nice to have a set of mounting bolts, however since it can be mounted in various configurations, I can see why they didn't include bolts since they'd have to supply several sets for the various mounting options. I mounted mine to a thin piece of wood in one of my cabinets initially with wood screws, but had to purchase some actual nuts/bolts/washers for a secure fit. Turning the knob to the various positions puts some serious torque on the unit, so a secure mounting job is required and the original wood screws in the pictures didn't last long. If you are mounting to a thicker panel, regular screws might work. Of course, you may want to mount it in one of the different configurations. Wiring is straight forward and I trust this will function for a very long time. Both batteries connect to the switch, which in turn powers a Blue Sea Systems ST Blade ATO/ATC Fuse Block, (https://amzn.to/2ZgpiPw - see picture) which in turn powers all the various and numerous 12v accessories in my van. This makes a great match for safely routing 12V throughout the van using two batteries. I'll update this review should the unit fail or give me problems in the future, but for now, I'm super happy. I could have spent a little less on a lesser known brand of switch, as there are many choices on desertcart, but Blue Sea Systems has a great reputation and I felt like it was worth a few extra bucks. I really don't want to burn down my van due to some cheap electrical switch!
