Specifications and Materials

This lever-style master switch is engineered for high-current service typical of trailer electrical systems, with heavy terminals for main battery circuits and auxiliary posts for control circuits where fitted. For Narva’s official range information and wiring guidance, see the manufacturer technical page.

Compatibility and Fitment

The Narva Lever Battery Master Switch Index Post suits 19mm panel mounting and is commonly used as the primary isolation point for battery systems on trailers, plant, and service vehicles. Use appropriately sized cable lugs, torque fasteners to spec, and ensure the switch interrupts the correct side of the circuit per site policy.

Compliance and Safety

Isolate the battery before installation. Ensure all terminations are clean, tight, and supported to avoid heat build-up. Use correct fuse or circuit protection upstream as required by your application and local regulations. After installation, verify off-state isolation and check for unintended loads.

Trailer Applications

Ideal for heavy trailer battery isolation, workshop safety lock-outs, and service disconnects on auxiliary systems. The lever action provides quick visual confirmation of isolation during maintenance or storage.
