Specification Material: Brass metal and plastic Color: Red + black Diameter: 57 mm (2.24 inches) Total height: 110 mm (4.33 inches) Width between two holes: 38 mm Voltage: 12 V / 200 A Weight: 120 g (0.26 lb) Package includes 1 x battery switch 2 x keys 1 x waterproof cover Note: Please check the picture and size carefully before purchasing Review: Easy to install, positive action - I bought this to disconnect a winch live feed when not in use. I was told it needed to be rated at 200A but that seems excessive and have no doubt this item will be more than up to the task. It has a very positive action when the red key is inserted and the brass terminals look built to last. I have installed it on a tractor so there is lots of vibration but a blob of silicone sealant on the threads will ensure they never loosen off. I bought a set of ring terminal fittings at the same time rather than loop the copper around the nut and crush it down. No point taking a chance. Despite the agricultural installation I didn't want it to look butchered. I found with a 22mm (I think) drill bit, I could put a hole in a flat bit of dash and push the isolator through from behind. This way I have only 2 small bolt heads showing which secure the isolator body, and the turret for the isolator key which is covered by a rubber cap when not in use. All looks neat and professional, and the item is well worth the money.

It won't fit directly to a battery unit. **Q: Will the car or device be damaged if someone attempts to start the car with the cutoff switch engaged?** A: The ignition creates a circuit to start the vehicle, this will break that circuit. Simple in an older vehicle but in a modern vehicle with anti theft devices and fancy electrics it could do anything **Q: Can I use this isolator for my 12 volt shed alarm in reverse logic? when i set the alarm at night i remove the red switch but power stays on.** A: Afraid it won’t work. The key is required to make the switch which it does via a pin in the side. When you remove the key the switch is therefore in the disconnected position. You could modify the key by splitting the shaft ? but suggest a key switch would be better. Old ignition switch ? **Q: Will this work for lotus elan m100** A: Should do any vehicle with a cabled battery connection. Chose a position to discreetly access the key. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Easy to install, positive action *by P***S on 25 January 2021* I bought this to disconnect a winch live feed when not in use.
