Pollak 51-916 Master Disconnect Switch with Removable Key – 180A, Weatherproof

The Pollak 51-916 Master Disconnect Switch offers a unique combination of electrical safety and vehicle security. Unlike standard lever-operated switches, the 51-916 features a removable key that allows you to lock the battery in the "Off" position. This makes it an essential tool for preventing unauthorized vehicle use, deterring theft, and ensuring the battery doesn't drain during long periods of inactivity.

Built to withstand the rigors of heavy-duty applications, this switch is housed in a one-piece die-cast metal casing and is environmentally sealed to perform in the harshest road and weather conditions.
