Pushbutton Switches

Pushbutton Switches are widely used in industrial and consumer applications. They are excellent devices for achieving a variety of control functions. The A22E-M-11-EMO is a Pushbutton Switch that is specifically designed to provide for two or three-position Operation, a secure snap action and secure contact closing.

Application Field

The A22E-M-11-EMO Pushbutton Switches are suitable for applications where a wide range of control is involved such as domestic and industrial control circuits. They can be used in both alternating current and direct current circuits, and also in mains switching applications. The range of available control functions allows the A22E-M-11-EMO Pushbutton Switch to be used in many different applications.

Design Principle

The design of the A22E-M-11-EMO Pushbutton Switch is based on the principles of electromagnetic and mechanical operation. A series of electromagnets, or coils, and an array of movable contacts are used to effect operation. The coils are energized by the current through the circuit and cause the provision of the contact closing when a button is pushed or a lever is moved. The contact closing is then maintained until the button is released or the lever is reset.

Operation

The operation of the A22E-M-11-EMO Pushbutton Switch is quite straightforward. When the button is pushed it energizes the coils. The magnetic field created by the energized coils attract the movable contacts to the fixed contacts, causing the contact closing. When the button is released the movable contact is reset. The control action can also be achieved by a lever operated switch, in which the lever moves the contacts to the required position.

Functional Parameters

The A22E-M-11-EMO Pushbutton Switch is exceptionally reliable and robust in operation. It’s environmental rating is IP66, making it suitable for a wide range of industrial environments. The switch has a rated voltage of 220V AC and a rated current of 20A. The maximum switching power for the switch is 4400VA. The available contact forms are DPDT (2NO) and 3PDT (3NO).

Safety Features

Safety is of paramount importance with any electrical device, and the A22E-M-11-EMO Pushbutton Switch has been designed with several safety features. Protective covers are provided to prevent accidental contact with the switch terminals, and the mechanical phenomenon of accidental energization due to contact with other components is greatly reduced. The encapsulated design prevents the ingress of moisture and dirt and further enhances safety.

Conclusion

The A22E-M-11-EMO Pushbutton Switch is a reliable and robust device for two or three-position operation, providing secure contact closing and secure snap action. The range of available control functions allows the switch to be used in a wide range of applications, from domestic to industrial control circuits. The range of safety features incorporated into the switch adds additional protection, making it suitable for use in a variety of challenging environments.
