Honeywell Technologies AML Series Push Button Switch 2PDT, Front Panel Mount, Red/Green/Black/Yellow AML21BBA2AC

The Honeywell Technologies AML Series AML21BBA2AC push button switch is engineered for industrial, automation, and electrical panel applications where robust manual control and dual-circuit switching are required. Featuring a front panel mount construction, this switch incorporates a flame-retardant, glass-reinforced polyester body with a rectangular polycarbonate plunger. The actuator is available in multiple high-visibility colours - red, green, black, and yellow - facilitating clear functional identification in operator stations and control panels.

This model offers a momentary action, making it suitable for use as a press-to-reset or press-to-start device in operational circuits. The 2PDT (double pole double throw) contact configuration supports switching two separate electrical circuits simultaneously, enhancing flexibility for integration into complex panel layouts or machinery interfaces. The unit’s IP67 sealing provides robust protection against dust ingress and water immersion, ensuring reliable operation in demanding industrial or outdoor environments where moisture and debris may otherwise compromise functionality.

The front panel mount design allows the switch to be securely installed flush with the panel surface, reducing the risk of snagging and simplifying both assembly and maintenance. Solder type terminals offer secure electrical connections to PCBs or wiring harnesses. Designed to operate reliably across a temperature range from 0°C to 55°C, the AML21BBA2AC switch is suited to both controlled indoor systems and installations exposed to elevated ambient conditions.

This non-illuminated actuator is intended for applications where external indication, signage, or the actuator’s colour provides sufficient operator feedback. Glass-reinforced polyester construction delivers enhanced resistance to mechanical stress and long-term durability, while the polycarbonate plunger ensures consistent tactile response through repeated operation. Compliance with UL 1054, CSA 22.2, UL 496, and related electrical approval standards certifies suitability for safety-critical and regulated panel installations.

Typical industrial applications include factory automation control panels, operator consoles, production line reset or start stations, and multi-function switchgear in electrical distribution systems. The multipurpose contact arrangement and panel-mounting flexibility also make this switch valuable for laboratory benches, test systems, and maintenance panels where secure, sealed manual switching is necessary.

For industrial users seeking a durable, high-protection, non-illuminated push button capable of dual-circuit operation and broad usability across challenging environments, the Honeywell Technologies AML Series AML21BBA2AC is an optimal choice.
