Heavy duty TIR battery isolator/master switch rated at 250A (continuous) and 24V max. with a removable key on a 200mm chain lanyard, ideal for higher current applications on cars, boats, motor homes, horse-boxes, trucks, commercial vehicles etc.

Can be used to isolate the power source in an emergency (kill switch), prevent battery drain if the vehicle is left for long periods and as an anti-theft device.

The switch and key are fitted with individual splash-proof covers so the switch is protected from water ingress when the key is both in place and removed.

Sold individually. Fixings not included.

Note: If this switch is used to isolate the vehicle's starter battery it should not be operated when the engine is running (except in an emergency situation) because there is a high risk of damage to the alternator and other parts of the vehicle's electrical system.

I needed to renew my boats main battery breaker switch but where to buy? 12V Planet of course! I have never been disappointed with any item bought from you as you take care not to sell inferior products.

Exact match

Needed two of these to replace ones that had got water damaged. These were the exact replacements to the originals I already had and are ideally matched for the systems on my boat.
