LAY5-BA51 Industrial Flush Yellow Momentary Push Button Switch
The LAY5-BA51 Push Button Switch is a heavy-duty, commercial-grade industrial control switch engineered for precise command signaling, system reset functions, and interlocking operations within automated machinery and electrical control panels. Built into a standardized 22mm mounting cutout profile, this operator station component features a premium die-cast zinc alloy metal base body paired with high-grade, flame-retardant plastic to ensure robust mechanical resistance to vibration and physical shock on the factory floor.
Operating with a smooth momentary spring-return mechanism, this switch features a flush, unmarked yellow push button that operates a single Normally Open (1 N/O) modular contact block. The internal electrical design utilizes high-conductivity silver alloy contacts with self-cleaning capabilities, guaranteeing flawless low-voltage control routing for magnetic starters, motor contactors, automated relays, and PLC control circuits.
