Homer Battery Isolator Switch BIS1

The Homer Battery Isolator Switch, part number BIS1, is a simple manual switch designed to isolate the battery when a vehicle is not in use. It is listed as a switch sold each, with no warranty noted, and it sits in the auto elec accessories group under fuses, breakers, relays and switches.

Because no vehicle fitment list is supplied, the important checkpoints are the BIS1 part number, the product type, and the intended use. Buyers should match the application carefully, especially where battery access, power shut-off needs, and installation space matter. This is a universal-style accessory rather than a model-specific part.

For owners who need a battery isolation switch for storage, maintenance, or to disconnect power manually, the Homer BIS1 offers a clear and direct solution. It is an each item, and the stated turn-knob operation keeps the function easy to understand before installation.

Application and Buying Notes

Confirm the BIS1 part number before ordering, as there is no vehicle make or model fitment list provided here. This switch is described as a battery isolator for automotive and marine use, so it is best matched by application requirements rather than by a specific vehicle listing.

Check that you want a manual isolator style switch, because the stated function is to isolate battery power by turning the knob. If your setup needs a different battery management method, confirm the control style and installation approach before purchase.

The no warranty listing is also worth noting when planning the job. As with any electrical accessory, you should confirm that the switch location, access to the battery, and space for the knob operation suit your installation, especially where the battery is regularly isolated for storage or servicing.

This is a straightforward accessory in the auto electrical category, not a vehicle-specific module. That means the safest purchase check is to compare the part number BIS1 with your required isolator switch function, then confirm the application is appropriate for either automotive or marine use.

Before supply, the safest approach is to confirm the original unit details against the listed part number, voltage, output rating, mounting arrangement, and pulley configuration. That checking process is standard practice in the parts trade because visually similar units can still differ in service-critical ways.

For workshop, fleet, and equipment applications, accurate identification of part number BIS1 helps avoid unnecessary freight, additional labour, and vehicle or machine downtime. Where the application is not straightforward, the original unit, OEM reference, or workshop records should be used as the primary confirmation point.

BATTERY ISOLATOR SWITCH. Part number BIS1 should be checked first. These details form the core reference points used by parts interpreters when confirming the correct replacement.

For part number BIS1, the normal identification sequence is part number, electrical rating, mounting arrangement, connector or terminal style, and pulley or drive details. Using those checkpoints helps confirm that the listed unit matches the service requirement rather than only looking similar.

For a switch in workshop, fleet, trade, agricultural, or construction service, the listed electrical specification should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Where no verified application list is available, the part number, mounting details, connector style, and published specifications should be used as the primary selection criteria.

In the absence of a verified fitment list, the safest approach is to compare the removed unit directly with the listed product details. That includes checking the housing style, pulley layout, regulator arrangement, and any visible identification numbers before supply is approved.

The listed warranty is No Warranty. Warranty terms should be considered alongside correct application and part identification, as warranty does not replace fitment confirmation.

Compatibility note: Please confirm compatibility by checking part number BIS1, the manual turn-knob isolator function, and whether your application is automotive or marine. No vehicle-specific fitment list is supplied, so final suitability should be verified against the installation requirements of your vehicle or vessel.
