Rotary Switches – 42A36-01-1-09N Application Field and Working Principle

Rotary switches, also known as rotary selector switches, are among the oldest switch designs and use Detent, Rotation, and Key Action to provide reliable circuit connection through rotating, many-faced wafers or cams. These switches were originally developed in the late 19th century with mechanical gears, levers, and linkage, but have since been widely integrated into many modern electronic applications for control and automation operations. By selecting different positions, the switches can be used to control alarms, doorbells, dimming, volume adjustment, and more.The 42A36-01-1-09N rotary switch is a type of rotary selector switch, usually found in opto-electronic applications. Designed with a small-form-factor, the 42A36-01-1-09N exhibits a 36-position switching action to provide reliable control of LEDs and other lighting devices. Equipped with a modular PCB, the 42A36-01-1-09N is relatively simple to install, operate and maintain.

Application Fields

The 42A36-01-1-09N rotary switch provides an effective means to adjust and control various electronic products such as led-lighting, studio lighting, household appliances, dimmers and switches for many commercial, industrial and residential electronics. Their long-life-cycle, up to 120,000 operations, and reliable switching action makes them a preferred choice for many modern electronic operations.

Working Principle

The 42A36-01-1-09N rotary switch utilizes a two-position switch to combine two different contact options, thus providing 36 different switching options. A shaft is used to rotate the multiple cams connected to the switches, thus operating a variety of electrical functions. Firstly, the single actuating knob is turned until the desired position is reached. This rotation transmits a torque onto the cams, thus turning them. The cam turns into a position where the contact arms line up with their respective contacts located on the printed circuit board. The contacts are made with a spring loaded mechanism that allows for reliable switching.This two-position switch design makes the larger number of contact options available, thus allowing for the creation of many electrical applications. Additionally, by keeping the contacts facing upwards and the cams facing downwards, the 42A36-01-1-09N can be used in any environment, including harsh and humid conditions.

Conclusion

The 42A36-01-1-09N rotary switch is a dependable and versatile lighting control option. It is often chosen for its long life-cycle, reliable switching action, and explosion-proof ability. By rotating its multiple cams, the 42A36-01-1-09N is able to provide up to 36-positions of electrical control, making it the preferred choice for many opto-electronic applications.
