Battery isolator / cut-off switch with a removable key for use in cars and other vehicles. Complies with FIA regulations for track day and motorsport events. The hole in the key allows a remote pull cord to be fitted for external activation to isolate the battery in an emergency.

This switch also incorporates the following features:

• Ignition isolation - prevents potentially dangerous engine run-on (connection via 2 x 6.3mm male terminals)
• Surge protection - supplied resistor prevents alternator voltage spikes potentially damaging the alternator diodes and other parts of the electrical system when the switch is operated (connection via 2 x 6.3mm male terminals).

This switch is also useful for preventing battery drain if left for long periods or as an anti-theft device.

Fitted with cover to protect the keyhole when the key is removed.
