Precision Mechanics

The 502 Brass Rotary Switch is a 3 Poles (Pump + Swing) rotary switch rated 250V – 6AMP, moulded in 30% Glass-filled + Nylon. Every detent is set on precision tooling so the click stays crisp through years of daily cycling — no drift, no dead positions.

Terminal Integrity

0.5mm brass terminals resist pitting and hold torque under repeated tightening, keeping contact resistance low across the life of the cooler.

Built to Last

Assembled in-house at our dedicated rotary switch division, running since 2015. Wired for independent pump and swing control. Also available with tin terminals.
