This switch has proven to be an excellent addition to my DIY projects for my custom power bank. This 12-48 V battery power cut master switch is incredibly reliable and ensures a secure disconnect when needed. The on/off functionality is straightforward and easy to operate, providing peace of mind when isolating the battery for maintenance or safety reasons.One of the standout features is its robust construction. The switch feels solid and durable, capable of withstanding harsh conditions whether installed in a vehicle, RV, or boat. The installation process was simple and intuitive, with clear instructions that made it easy to get everything set up quickly.The only minor downside is that it could benefit from slightly larger terminal posts for easier connection with heavier gauge wires. However, this is a small issue compared to the overall effectiveness and reliability of the switch.I believe this switch is a highly recommended product for any DIYer looking to safely manage their vehicle or RV's battery connections. Its ease of use, solid build, and dependable performance make it a must-have for ensuring battery safety and maintenance.

Der Schalter an sich ist gut verarbeitet. Nach etwas mehr als einem Jahr hat der Schalter von jetzt auf gleich Übergangsprobleme wodurch die Solaranlage sich abgeschaltet hat.

こちらは中国からの発送で少し時間がかかりますが、とても良い商品でした。悲しいことですが、Amazonジャパンよりも中国の方が良いです。

Easy to install and works great,you need a lug with a size 10mm ringRecommend

I bought this to prevent small current drains from killing the battery on my 25ft travel trailer while it was in storage. Much easier than disconnecting a battery lead each time!The switch is a good, heavy duty design. I wanted to mount it so that I could shut off the battery power from the outside of the battery box. I didn't know if the supplied mounting screws would be long enough. Happily they are. I have a group 27 battery box with a group 24 battery. There was easily enough room to fit the switch inside the box and still fit the battery. The switch fit perfectly through a 2" hole and the supplied screws were long enough to secure it. I used 4 stainless steel washers from the local hardware store to complete the installation. A bead of silicon secured the back cover of the switch to make a nice, waterproof installation.One safety note. If using this on a trailer, it should be in the "off" position ONLY when the trailer is being stored! If you attempt to tow the trailer with it "off" position, two bad things can happen:1. Your tow vehicle can't charge your trailer battery.2. In the event of a trailer separation, the trailer brakes will not come on.
