Honeywell Technologies AML21 Series Push Button Switch, Front Panel Mount Black, DPDT, IP67

Honeywell AML21 Series Push Button Switch, IP67, Black Push Button - AML21CBA2AD

This push-button switch is a front-panel mounted control designed for momentary actuation in industrial electrical systems. It offers a sealed Interface for operators and integrates into control panels where a compact, rugged switching element is required without illumination. The unit is suited to environments demanding protected ingress and routine operator interaction while maintaining standard contact switching functionality.

Features and Benefits:

• IP67 rating provides dust-tight and temporary immersion protection
  2PDT contact arrangement allows switching of two circuits simultaneously
  Momentary actuation enables temporary contact engagement only while pressed
  Solder terminals facilitate secure wire terminations for PCB or harnessing
  Glass-reinforced PBT polyester body resists mechanical and thermal stress
  Rated for operation up to +55°C to withstand elevated ambient temperatures

Applications

• Suitable for control-panel operator inputs in automation systems
  Ideal for switching auxiliary circuits in electrical distribution panels
  Used for manual control in test rigs and bench equipment
  Can be used for machine stop/start functions requiring momentary action

What material composes the actuator and how does that affect longevity?

The button is moulded from polycarbonate, providing wear resistance to repeated mechanical presses and maintaining tactile integrity over many cycles.

How is the product mounted to a control panel?

It is designed for front-panel mounting, securing from the front face to allow straightforward installation and service access from the operator side.

Are there approvals relevant to industrial installation standards?

It holds recognised standards including UL496 and UL1054 as well as CSA22.2 approvals applicable to electrical switch devices.

What illumination options are available for integration?

This variant is non-illuminated and does not include built-in lighting, so external indication would require separate components.

Is the switch suitable for hazardous-area certified equipment?

It has no hazardous-area certification and should not be specified where such certification is mandated.
