The Pollak 31-603 Ignition Switch is the professional choice for fleet managers and equipment operators who require high-performance power control with the added efficiency of uniform keying. This 2-position "Off-On" switch is Keyed Alike to Code 556, allowing one key to operate multiple vehicles or machines—perfect for large fleets, construction sites, and agricultural operations.

Part of Pollak’s heavy-duty series, the 31-603 features a robust one-piece zinc die-cast housing designed to endure the vibration, dust, and moisture of industrial use. Inside, solid copper contacts and brass screw terminals ensure maximum electrical conductivity and a long lifecycle, even in high-demand 12V and 24V systems.

Designed to fit standard 3/4" diameter mounting holes, this switch is a direct replacement for many OEM ignition cylinders. Its simple two-terminal design makes it ideal for applications that don't require a momentary start position, such as auxiliary power control, lighting circuits, or stationary industrial engines.
