2Pcs Battery Car Off Spare Switch Universal Key Cut Power Isolator Kill Au Stock

A battery isolator is only as useful as the key that turns it. Lose the one that came with the switch and the isolator is stuck wherever you left it, often in the off position, in a shed, on a Sunday. This two-pack puts a spare in the glovebox and another on the workshop board.

Spares, not the switch itself

Read the packing list before ordering. The supplier gives the contents as 2PCS x Isolator Switch Keys and nothing else: no switch body, no terminals, no hardware. It suits someone who already has an isolator fitted and wants a second or third key for it. The keys are the common red pattern used on universal isolators, but no brand, model or switch series is named, so compare the photos against the key you already have.

Red plastic, 43 x 50 mm

The moulding measures 43*50mm, small enough for a keyring yet not so small it vanishes into a toolbox. Red is practical rather than decorative. An isolator key lives around an engine bay or battery box, and a bright moulding is easier to find under a torch and easier to notice when it has been left sitting in the switch.

Key features

• Two per pack: one to carry, one kept where the household can find it.
• 43 x 50 mm moulding: big enough to grip with cold or greasy hands.
• Red colour: stands out against a dark battery box.
• Keys only: replaces a lost handle, not the isolator itself.

Using an isolator safely

• These keys carry no electrical rating of any kind. If you are buying or replacing the switch itself, that switch must be sized to the cable and the load it interrupts and wired in by a qualified auto electrician. An under-rated isolator in a battery circuit is a fire risk.
• Do not switch a battery isolator off while the engine is running unless the switch manufacturer states it is safe to do so. Opening the circuit under load can damage the alternator and the vehicle's electronics.
• Check the key profile against your existing key or switch before ordering, since the supplier does not list the switches these are cut for.
• No approval or standard is named for these keys, so none is claimed here.

The supplier asks that spares be stored somewhere safe to avoid loss, which is sound advice for a key this easy to put down and forget.
