Pollak 31-600 3-Position Ignition Switch – On-Off-On Maintained (No Spring Return) – 3 Screw Terminals – Heavy-Duty Die-Cast

Specialized Maintained-Position Control for Industrial Applications

The Pollak 31-600 3-Position Ignition Switch is a high-reliability electrical component designed for applications requiring a "Maintained" position rather than a momentary start. Unlike standard automotive ignitions that spring back from the start position, the 31-600 features an On-Off-On logic with No Spring Return, meaning the switch stays in the selected position until manually moved.

Constructed with a rugged one-piece zinc die-cast housing, this switch is engineered to endure the mechanical stress and environmental challenges of the trucking, marine, and industrial sectors. The 3-screw terminal base provides a high-torque, vibration-resistant connection point, making it the ideal choice for heavy machinery and custom electrical panels.

Key Features & Benefits:

• Maintained 3-Position Logic: Functions as On – Off – On, perfect for dual-battery systems, manual toggling between two accessory circuits, or specialized motor controls.

• No Spring Return: The switch stays in the position you set—no momentary "Start" action.

• 3-Screw Terminal Base: Ensures a permanent, high-conductivity connection that won't vibrate loose, even in high-impact environments.

• Heavy-Duty Construction: One-piece zinc die-cast housing and solid copper contacts provide long-term durability and minimal voltage drop.

• Environmental Protection: Features internal O-ring and lip seals to protect internal components from moisture, dust, and corrosive grime.

• Various Keyed Security: Shipped with individual key codes (Various Keyed) for unique security across different installations. Includes 2 keys.
