Advanced Safety & Reliability

This universal-keyed switch features a 4-position configuration (Accessory, Off, On/Accessory, and Momentary Start). It is equipped with a patented starter lockout feature, which prevents the operator from accidentally restarting the engine while it is already running—protecting your starter motor from damage. The internal mechanism is lubricated for a smooth feel and a long service life of up to 50,000 cycles.

Weather-Resistant Engineering

Designed to withstand harsh conditions, the Pollak 31-610 includes a weather-resistant O-ring seal and a specialized lip seal to prevent moisture and dust from entering the contact chamber. Solid copper contacts and brass terminals ensure maximum electrical conductivity and corrosion resistance.
