Overview

Quikcrimp Battery Master Switch 100A 12V is a heavy duty battery cut-off switch for isolating a 12V battery circuit when a vehicle, trailer, service body or auxiliary battery setup is parked, serviced or stored.

The removable key gives a simple physical isolation point, helping reduce unwanted battery drain and preventing the circuit from being switched back on without the key fitted.

Features

• Heavy duty battery cut-off switch.
• Rated to 100A at 12V.
• Includes removable key.
• Supplied as one switch.

Compatibility and Fitment

Check the battery circuit load, cable lug size, panel thickness, mounting clearance and key access before ordering. The main mismatch risk is fitting a 100A battery cut-off switch into a circuit that needs a higher continuous current rating.

Mount the switch where the key can be reached easily but where the terminals and battery cables are protected from accidental contact, vibration and moisture exposure.

Check the related isolation parts below against the vehicle, trailer or battery setup before ordering.

Compliance and Safety

Disconnect the battery before fitting the switch. Use correctly sized cable lugs, tighten all terminals securely and protect exposed live connections so vibration cannot loosen the cable or create a short circuit.

Trailer Applications

Workshops fit battery master switches to trailers, service vehicles, caravans, auxiliary battery systems, plant equipment and marine-style 12V setups where battery isolation is needed during storage, transport or maintenance.
