When it comes to selecting pushbutton switches, their application field and working principle depend on their designated use. The A22-HW-11M pushbutton switch is designed for various applications and its size is 13mmx19mm. It is a single pole, single throw push button switch rated for 10A @ 250VAC or 10A @ 28VDC.

Functionality of A22-HW-11M Pushbutton Switches

A22-HW-11M pushbutton switches are most commonly used to provide a control signal to either connect or disconnect electrical circuits. Each contact within the pushbutton switch is associated with a particular position of the switch and can either be open, closed, or somewhere in between. Depending on the application and design requirements, these pushbutton switches can act as either normally open (NO) or normally closed (NC) contacts, which respectively indicate that the switch is initially open or closed when it is not actuated.

Principle of Operation of A22-HW-11M Pushbutton Switches

The operation of A22-HW-11M pushbutton switches is fairly straightforward. The switch requires a single pole mechanism to work, which allows the switch contacts to be closed and opened from a single control. When the switch is in its rest position, the contact points remain open and no current is allowed to pass through the circuit. When the switch is pressed, the contact points are closed and a current is allowed to pass through the circuit. The contacts then remain closed until the switch is released and returns to its rest position.

Applications of A22-HW-11M Pushbutton Switches

The A22-HW-11M pushbutton switch is used in a wide range of applications, including industrial controls, communications, computers, home appliances, security, medical, automotive and aerospace applications. In certain applications, this type of switch may be used as part of a safety system, such as an emergency stop switch. Additionally, due to their highly reliable operation and contact protection, these switches are often used in harsh, hazardous, or wet environments. Depending on the design, some A22-HW-11M switches may also be rated for IP67 waterproof protection.

How to Select A22-HW-11M Pushbutton Switches

When selecting an A22-HW-11M pushbutton switch, it is important to consider all of the factors involved in its use, including the working environment, application, size, current, voltage, actuation force, and the expected life expectancy. Additionally, it is important to understand the capabilities and limitations of the switch to ensure it can meet your specific needs. Lastly, it is important to select a switch that is manufactured according to the appropriate set of safety standards, such as UL, CSA, and CE.

Conclusion

The A22-HW-11M pushbutton switch is a highly reliable and versatile switch that can be used in a variety of applications. It is important to consider all of the factors involved when selecting an A22-HW-11M switch for a particular application to ensure the switch meets the required requirements. Additionally, it is important to select a switch that is manufactured according to the appropriate safety standards.
