Product Overview
HOSONG 40mm annular power illuminated push button is a flagship power control switch exclusively for super-large heavy-duty and special industrial equipment. Adopting the industry’s super-large standard Φ40mm mounting hole and a dual independent lighting system of panoramic annular running light + central power symbol light, its dual-layer light logic accurately distinguishes multiple equipment states including power-on standby, full-load operation and fault warning. It supports full voltage compatibility and multi-color customization, with built-in high-reliability 1NO1NC composite contacts supporting switchable momentary and latching modes to match electric control logic of various large equipment. The ultra-thick integrated sealed metal housing features IP67 waterproof and IK10 super impact & vibration resistance, with excellent resistance to extreme temperature difference, severe corrosion and violent vibration, serving as a top-tier power control option for super-large equipment in mining, engineering and outdoor energy storage fields.
