Honeywell Short Roller Lever Micro Switch Screw Terminal 15A 125V AC SPDT BZ-2RW822-A2N138

The Honeywell BZ-2RW822-A2N138 is a premium short roller lever micro switch, designed for high-reliability position detection and control functions in automated systems, mechanical equipment, and industrial safety circuits. It supports a switch contact current of up to 15A at 125V AC, offering robust capability for electrical load handling and switching tasks.

The switch operates using a short roller lever actuator, which ensures consistent actuation for position sensing on moving mechanical parts and provides rapid, repeatable contact changeover. Its SPDT (single-pole double-throw) contact arrangement lends greater design flexibility, enabling integration into a wide variety of circuits for switching between normally closed and normally open states as required by control logic or safety needs.

Structured with a phenolic resin housing, this micro switch delivers excellent electrical insulation and mechanical durability, making it suitable for installations exposed to vibration, varying ambient temperatures, or demanding duty cycles. Screw terminals provide a secure connection that resists loosening in industrial environments, ensuring stable electrical performance over the device's long lifespan.

This model is rated for continuous mechanical operation across a remarkable 20,000,000 cycles, minimizing required maintenance and ensuring unwavering reliability in repetitive operation scenarios such as conveyor systems, assembly machines, or actuator feedback. The 1.67N actuation force requirement provides predictable triggering points, supporting precise feedback in critical sensing or interlock roles.

Operational across an extended temperature range from -55°C to 85°C, the BZ-2RW822-A2N138 performs reliably in both low and elevated temperature environments, making it compatible with outdoor or process-industrial machinery, refrigeration units, or high-temperature manufacturing lines.

Typical industrial use cases include serving as a safety interlock in electrical control panels, providing position feedback on mechanical actuators, limit sensing in automated production lines, or status indication in material handling equipment. The UL and CSA certifications enable acceptance in engineered industrial and commercial systems worldwide.
