We supply a range of battery isolator switches to suit all applications.
All are suitable for 6 and 12 volt batteries, positive or negative earth. The heavy duty types are designed to be able to handle 24 volt, but will obviously cope with less voltage vehicles just as well.
Direct-fit-to-battery type isolators are designed for fitting on the earth terminal as fitting to the positive terminal carries a danger of sparking when activating.
As well as the well-known safety advantage of a battery switch (which is why they are mandatory when racing to FIA & MSA requirements), they also deliver these benefits:
- Reduce risk of electrical shorts & fires
- Quickly isolate your battery for safe vehicle servicing
- Discourages unauthorised use/theft (remove key)
- Cures slow battery drain which can be a problem on vehicles only used intermittently or stored for extended periods
