Pushbutton switches have been used in various applications for decades as a flexible, reliable method of adding manual control and operation to systems. The A22R-FY-02M is a popular pushbutton switch that is widely used in a variety of applications. This article will discuss the application field and working principle of the A22R-FY-02M switch.

A22R-FY-02M Application Field

The A22R-FY-02M switch is a two pole, single throw, illuminated pushbutton switch. It is designed for use with 12, 24 or 48 VDC circuits, making it an appropriate choice for a variety of DC applications from controls, machines and systems to general purpose industrial equipment. The wide voltage range and heavy-duty contact rating make this switch suitable for usage in high-amperage circuits, including the operation of motors and solenoids. In addition, the switch features a clearly visible illuminated ring, making it a desirable choice for noise-prone or hazardous environments where a visual indication of circuit operation is required.

In comparison to standard mechanical pushbutton switches, the A22R-FY-02M has a more robust design. Its box-style fabrication features an integrated dust seal and gasket, allowing it to withstand harsh environment conditions and prolonged contact pressure, making it an ideal choice for applications where protection against dust, water and moisture is essential.

A22R-FY-02M Working Principle

The A22R-FY-02M operates by means of a plunger within the switch. This plunger transmits the manual motion of the actuator to a contact disc, which controls the on/off operation of the switch. A spring is used to ensure the plunger returns to the resting position once the manual motion has been completed.

When the plunger is depressed and the switch is in the Closed position, a contact rate of up to 10A at 250V AC or 10A at 30V DC is achieved, allowing it to be used in both alternating current and direct current circuits. The switch also features a thermoplastic ratcheting housing, which helps ensure that the switch remains in the On position while the plunger is depressed.

In addition to the illuminated ring, the A22R-FY-02M is also available with an optional audible indicator. When the switch is in the closed position, the actuator makes a distinctive “click” sound to indicate the circuit is active. This feature is especially beneficial for applications that require feedback about the switch’s State, such as in power management systems.

Conclusion

The A22R-FY-02M switch is an economical, robust pushbutton switch that is suitable for a wide variety of applications. It features a wide voltage range and heavy-duty contact ratings, as well as an integrated dust seal and gasket that allow it to withstand harsh environment conditions and prolonged contact pressure. Additionally, the switch is available with both illumination and audible indicator options, making it an ideal choice for noise-prone or hazardous environments.
