Rotary Switches

Rotary switches are a type of machine switch which use a manual rotation of a switch selector handle to enable or disable a device or to control multiple circuits. The A20303RNZQ is a rotary switch specifically designed for applications with a broad range of uses including automotive, home appliance and electric systems.

The A20303RNZQ has a robustly built construction which includes an anodized aluminum body and an IP67 enclosure rating, making it suitable for use in a wide variety of applications in challenging environments. It is also designed for ease of installation with a snap-fit design and screws for mounting. The A20303RNZQ is a 15A rated switch and is UL, CE, and RoHS compliant.

A20303RNZQ Application Fields

The A20303RNZQ rotary switch is suitable for a wide range of applications, including automotive and home appliances. Automotive applications include memory recall or operation of electric windows, sunroofs and other accessories. In home appliances, it can be used as a fan speed control, controlling the fan speed as needed. It can also be used to control lighting systems.

The A20303RNZQ rotary switch can also be used for industrial and HVAC applications. Industrial applications include controlling motor speed, valve and pump controls as well as process monitoring. In HVAC applications, it can be used for temperature control, fan speed control and other HVAC applications.

A20303RNZQ Working Principle

The A20303RNZQ rotary switch works on a simple principle, when the handle is rotated, the contact surfaces between the switch poles and the corresponding terminals come into contact, completing the circuit. This will enable or disable a device, or control multiple circuits depending on the various configurations. The handle has up to five positions and is used to select which circuit or device to enable or disable.

The contact is maintained while the handle is in one position as long as a small spring force is applied to keep the contact in place. The contact is released when the handle is rotated and the handle is gradually returned to its original position by a detent mechanism. This provides a secure holding place for the switch, ensuring that the handle will not rotate accidentally.

Conclusion

The A20303RNZQ is a versatile rotary switch suitable for a wide range of applications, from automotive and home appliance to industrial and HVAC. It is a robustly built switch with an anodized aluminum body and IP67 enclosure rating, making it suitable for use in challenging environments. The A20303RNZQ works on a simple principle, and is designed with ease of installation in mind.
