Rotary Switches - 09M30-04-1-03N Application Field and Working Principle

Rotary switches, which use a rotating knob, lever, or dial to select an electric signal, are commonly used in electronics and control systems. The rotary switch has a few different subtypes, including the 09M30-04-1-03N switch. Let’s take a look at how the 09M30-04-1-03N works as well as its application field.

Form and Structure

The 09M30-04-1-03N rotary switch is a miniature design for needing limited space, and it is a polarized type switch. The body is adopting high temperature plastic shell and there are 2 terminals which is 2.3mm apart. The dimension of the whole switch is only ⁵⁄₈” x ⁹⁄₁₆”, which is quite small and practical.

Working Principle

The 09M30-04-1-03N rotary switch is a SPDT (single pole double throw) on-off type switch, which means it can be used to control the switch between two different connections. It consists of a rotating member and a spring-loaded contact arm that connects with the cam when the control knob is turned. When the control knob is rotated, the contact arm moves along the cam, allowing the circuit to activate either one of the two connections or to turn off the circuit completely.

Fields of Application

The 09M30-04-1-03N rotary switch is commonly used in various applications, such as home appliances, industrial devices, audio and video equipment, electronic musical instruments, gasoline engines, pumps, adjusters, and machine tools. It is also used in communication, aviation and military equipment, as well as other multiple applications.

Conclusion

The 09M30-04-1-03N rotary switch has a miniature design and it is easy to install with limited space. It is usually used in home appliances, industrial devices, audio and video equipment, communication, aviation and military equipment, etc. It works on the principle of a rotating member and a spring-loaded contact arm that connects with the cam when the control knob is turned.
