Battery Switch 12V-24V Top Post Battery Disconnect Switch Battery Main Switch Isolator for Negative Power Cut Off (Brass Wing nut Version)

It is easy to install and does what it claims to do, I have used others on Amazon with less-than-stellar results. I would recommend this one as my goto disconnect.

Works great

lol Checked resistance before I installed it; that turned out great! Great item for those that don’t drive their vehicle/s often. Saves your battery from being drained due to vehicles power draw.

Easy to install and use does the job well would recommend

Installed on cranking battery on the boat. Stopped a current leak somewhere in the outboard motor that was draining the battery. Very easy to install, fast and simple disconnection of battery voltage.

Fácil de instalar y manipular. Con un medio giro corta inmediatamente la corriente de alimentación al vehículo, además, los materiales se ven de buena calidad, duraderos y el diseño se ve estéticamente agradable a la vista. Recomendado 100%. Gracias y saludos

This switch works as it should: disconnects an electrical circuit and connects it back when needed. It is quite easy to install and operate. Just loosen up the green knob to turn off the power and tighten it up to turn on. The switch is made out of good material. There is not much to add - it works.
