LAY5-BA11 Industrial Flush White Momentary Push Button Switch
The LAY5-BA11 is a heavy-duty, commercial-grade industrial control switch designed for reliable command signaling, panel configuration reset, and custom contact interlocking within automated machinery and electrical distribution boxes. Engineered to mount seamlessly into standardized 22mm mounting cutout profiles, this compact operator interface features a premium die-cast zinc alloy metal collar base body combined with a high-grade, flame-retardant plastic frame to resist rigorous mechanical handling and harsh vibrations on the factory floor.
Operating via a smooth momentary spring-return mechanism, this switch is equipped with a high-visibility, flush, unmarked white push button that drives a single Normally Open (1 N/O) modular contact block. The internal component path relies on high-conductivity silver alloy electrical contacts featuring dual-switching and self-cleaning actions, ensuring reliable low-voltage control routing for magnetic starters, motor contactors, PLC digital inputs, and automated relays.
