Rotary switches are electrical components used to select one of multiple circuits by rotating a spindle connected to a set of contacts.(1) 423512-1-03N is a kind of rotary switch among hundreds of kinds available in the market. It offers a range of versions with different actuators, terminations and switch functions, making it very flexible. This article will discuss the application field and working principle of 423512-1-03N.

In terms of application, 423512-1-03N rotary switch finds its ideal use in consumer electronics, telecommunication and automotive industry. Due to its structural simplicity, it can also be used in a wide range of low current applications such as control, lighting and air conditioning systems. These electronic components are mostly unipolar, meaning the current will travel in one direction. In addition, 423512-1-03N rotary switches have a rich selection of pole or throw (SPDT, DPDT, SOT, etc.) selections, providing customization options for consumers.

423512-1-03N rotary switch works based on the same principle as other electrical switches. It also has a wiper fingerprint blade which contacts the electrical wear parts (the contacts or wheels) as the rotary knob is rotated. The wiper blade is basically responsible for the physical contact of the electrical connection and it is moved between different positions depending on the application. The switch is powered by a low current, usually milliamps, to control a larger mechanical power such as pumps, motors, etc. When in the right position, depending on the pole or throw selection, the connection of two contacts allows the current to flow through the circuit and make it work.

In comparison to other types of switches, 423512-1-03N rotary switches are more user-friendly, as they can be manually operated with the help of a rotating knob or handle, which makes it suitable for electrical applications. For adjustable applications, the rotary switch can also be equipped with various features such as mounting plates and caps, actuator handles, and other accessory parts for greater flexibility and convenience.

In conclusion, 423512-1-03N rotary switch is a vastly employed momentary contact switch based on the classic make-break mechanism. It enables a user to control multiple circuits with the simple turn of a knob or handle. It finds its use in a wide range of applications including consumer electronics, telecommunications, automotive industry and many more, offering consumers a wide range of options from different pole or throw selections.
