Honeywell AML Series Push Button Switch, IP67, Momentary Actuation - AML21BBA2AA

This push-button switch is a front-panel momentary control intended for industrial control and signalling tasks. It is built for regular operator actuation in electrical and mechanical systems, offering sealed ingress protection and a robust polymer construction suitable for use on control panels in production, test and maintenance environments.

Features and Benefits:

• IP67 rating provides dust-tight sealing and temporary immersion protection
  Glass-reinforced PBT body delivers enhanced mechanical strength
  1PDT contact arrangement enables single-circuit changeover switching
  Quick-connect terminals permit Rapid wiring and serviceability
  Operational range from 0–55°C supports typical industrial ambient conditions
  Rectangular polycarbonate button available in four colours aids Visual identification

Applications

• Suitable for operator control panels in automated production lines
  Ideal for emergency stop or start functions on machinery interfaces
  Used with control cabinets where sealed user interfaces are required
  Can be used for panel-mounted testing stations and commissioning rigs

What mounting method is required to install it from the front?

It is designed for front-panel mounting with a bezel that secures the switch into a cut-out and allows access only from the operator side.

How is the switch actuated and what is the contact behaviour?

The actuator is momentary
contacts change state only while the button is depressed, providing temporary make/break control of a single circuit.

Which Terminal arrangement simplifies connection to wire harnesses?

The device uses quick-connect terminals to enable straightforward push-on connections for fast assembly and field replacement.

Are illumination options supported and at what voltage?

The switch supports an illumination option rated at 24 V, while the supplied variant may be non-illuminated depending on configuration.
