Honeywell ALM21 Series Push Button Switch, IP67, Front Panel Mount - AML21CBA2AC
This push-button switch is a front-panel mounted, momentary control intended for industrial control and signalling tasks. It is constructed for use where a sealed Interface is required and provides a non-illuminated means of making or breaking circuits with a two-pole double-throw contact arrangement. The unit suits equipment requiring a robust, panel-mounted actuator and soldered electrical connections.
Features and Benefits:
• IP67 rating affords protection in wet or dusty conditions
• Momentary actuation provides temporary contact closure for control inputs
• 2PDT contact layout enables switching of two independent circuits
• Solder terminals ensure secure, low-resistance electrical joints
• Maximum operating temperature +55°C supports warm process environments
• Glass-reinforced PBT body resists mechanical and chemical wear
• Momentary actuation provides temporary contact closure for control inputs
• 2PDT contact layout enables switching of two independent circuits
• Solder terminals ensure secure, low-resistance electrical joints
• Maximum operating temperature +55°C supports warm process environments
• Glass-reinforced PBT body resists mechanical and chemical wear
Applications
• Suitable for industrial automation control panels requiring sealed switches
• Ideal for machine control start/stop inputs in harsh environments
• Used with control relays and Interface modules for dual-circuit switching
• Can be used for operator console functions in electrical cabinets
• Suitable for retrofit of panel-mounted controls where soldering is preferred

What material is used for the actuator and how does it perform?
The button face is polycarbonate, offering good impact resistance and dimensional stability under repeated pressing.
How is the switch mounted to a panel and sealed against ingress?
It is designed for front-panel mounting with an IP67 sealing standard to maintain ingress protection when fitted correctly.
Which safety or normative approvals apply to the design?
The construction meets recognised approvals including UL 496
43 & 55
UL 1054
and CSA 22.2 for electrical switch standards.
What environmental temperature range is acceptable for operation?
It operates reliably from 0°C up to a maximum of +55°C for typical industrial applications.
