Rotary Switches

Rotary switches are electrical switches consisting of a rotating insulating collar with a range of contacts connected to it. Contact selection is achieved by rotating the collar to align contact points on the outside of the collar with contact points on the body of the switch. The 093121-1-03N model of rotary switch is commonly found in a wide range of both electric and electronic applications.

093121-1-03N Application Field and Working Principle

The 093121-1-03N rotary switch comes in several versions with different types of selector contacts, shafts, and numbering systems. There are single-pole single-throw (SPST) and double-pole single-throw (DPST) versions available, both of which are able to support a current up to 6A. The switch is available with either a perpendicular or parallel piece of metal for the lever which is then rotated to set the contact points correctly. The metal then connects to the selector contacts on the rotating collar.

The 093121-1-03N is usually used for general purpose applications in low voltage, relatively low-current environments. Its usage is not limited to just electric, however; the switch can be found in many electronic applications as well. It is commonly used to switch on and off circuits in computers or to change settings on sound systems. It can also be used to control ventilation on HVAC systems, and is seen in some industrial processes.

Pronged Types of 093121-1-03N

The 093121-1-03N rotary switch is available in two main terminal types: pronged and chair-type. Pronged switches, also known as blade terminals, are the more common type and are used when soldering connections are not required. Chair-type terminals are used when soldering connections are required. Each type of terminal is identified by the shape of its contact points: the pronged type has a “V”-shaped indentation whereas the chair-type has a “U”-shaped indentation.

The 093121-1-03N is durable, reliable and flexible, and can fit into most applications thanks to its wide range of mounting types, poles, and actuation angles. It is the ideal choice for applications that require compact design, secure mounting and excellent dust-resistance.

Conclusion

The 093121-1-03N rotary switch is a reliable and durable electrical switch which is widely used in electric and electronic installations. It is available in several versions and two main terminal types: pronged and chair-type. Its wide range of mounting types, poles, and actuation angles make it a great choice for applications that require a secure and dust-resistant switch.
