503 Brass FR Rotary Switch (Fire Resistant) – 4 Poles (3 Speed), rated 250V – 8AMP, with Brass Terminal (0.65mm) and a 30% Glass-filled + Nylon FR body. Precision moulded and assembled in India.
The 503 Brass FR Rotary Switch (Fire Resistant) is a 4 Poles (3 Speed) rotary switch rated 250V – 8AMP, moulded in 30% Glass-filled + Nylon FR. Every detent is set on precision tooling so the click stays crisp through years of daily cycling — no drift, no dead positions.
Heavier 0.65mm brass terminals carry the full 8AMP rating without heat rise at the joint.
Assembled in-house at our dedicated rotary switch division, running since 2015. Moulded in fire-resistant nylon and easily compatible with H Frame motors – the specification for premium and commercial cooler builds.
