Rotary switches, such as 50D90-01-2-AJN, are basically a type of electrical switch where a circular rotor or wheel is rotated in order to select between a range of positions. These switches are used to make and break electrical circuits and are quite commonly used in the television and radio industry for selecting different channels, frequencies, and other relevant parameters. They are also used in the telecommunications industry for a variety of purposes, such as connecting and disconnecting telephone lines, as well as providing additional switching between different circuits. The rotary switch is one type of switch that has been in use for several decades now and is still very popular today.

The 50D90-01-2-AJN rotary switch, as an example of this type of switch, is a two-pole, one-position switch with a non-shorting, soldered terminal type. It has a double-mount terminal type, with solder in the body, and is capable of handling 10 Amps of current. Its contact ratings are 10 Amp 250 V AC maximum and 2 Amp 14 V DC. It also features a plastic, 2-piece housing, with a printed position mark, pressure spring switch actuator and a black plastic Insert. This particular switch has two rows of contacts, each with nine contact points, and includes an outer-rotor, inner-rotor, rotor shaft, and a plastic knob.

The 50D90-01-2-AJN rotary switch is designed and built for many applications including lighting, medical, military and telecom. With its plastic housing it is suitable for light commercial and residential use, and is available for mounting either in panel or board mount. It is also used in radio broadcasting and communications, testing and measuring equipment and even spacecraft.

The working principle of the 50D90-01-2-AJN rotary switch is quite straight-forward. A handle or knob is attached onto the rotor or wheel and when the handle is rotated one of the contact terminals is engaged with the rotor’s fixed contacts in order to complete an electrical connection. When the handle is rotated again, another contact terminal is engaged and the first connection is broken, thus providing the desired switching effect. The transition between these two points is smooth and silent, and the contacts remain secure on the rotor even when the handle is switched quickly.

The 50D90-01-2-AJN rotary switch is an example of a very common, reliable and versatile switch component. With an almost endless range of applications available to it, and a relatively straightforward design and setup, it is easy to see why it serves as an important component of many products in the telecommunications and radio industry. Its versatility and durability make it an excellent choice for a variety of tasks, and its popularity is a testament to its reliability and practical design.
