Precision Mechanics
The 503 Brass Rotary Switch is a 4 Poles (3 Speed) 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. Full three-speed control on a four-pole body. Also available with tin terminals.
