Battery Isolator Cut Off Switch - 12V/24V Automotive Emergency Power Kill Disconnector for Car

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.

Used as replacement for faulty one on the boat, working just fine

Simple to fit and good quality. Ideal for indoor use.

This is a sturdy, good quality electrical isolator switch, ideal for automotive use.

Nice quality, did the job it was required for it

Fitted as it has 10mm posts as opposed to the 8mm versions. Sturdy with decent size key. Does exactly what is should do.

Used to isolate a bow thruster, rated at 200 amps this works well. Quick delivery.

Ok, so, this does what it says on the tin and will safely act as a kill switch / on switch for 12v systems up to around 100 amps. However, it won't be suitable in all applications and this is because the rear part of the switch has no cover so the live terminals are exposed. This is fine if installing in a garage-type application where the rear of the switch may be recessed into a wall - however, in my application, as an isolator for a caravan motor mover - the rear is exposed under the front seat making it dangerous and not ideal for a storage compartment. I have used it, with plenty of insulation tape and will regularly check it's condition until i can find a more appropiate one.

Purchased before and they do what is required perfectly.

Fehlkauf, aber gutes Produkt.

Solide et bien pratique pour économiser la batterie lors des périodes de repos de ma R4. Même si c'est plus psychologique qu'efficace je m'en sers aussi comme antivol.

Super pièce de voiture qui fonctionne très bien correspond bien à mon véhicule, c’est bien d’avoir des pièces sur Amazon. Au moins on peut être livré plus rapidement et c’est pratique quand on trouve pas la pièce. Nulle part ailleurs.

Buon interruttore e robusto, ovviamente ho dovuto un po' ingegnarmi per fissarlo allo scooter ma non ci ho messo molto, funziona alla perfezione ed è molto comodo per attivare/disattivare la batteria ... scelta per me obbligata per problemi tecnici di accensione che ho risolto al minimo costo invece di una spesa superiore.
