Rotary switches are a form of electrical switch that use a rotating wheel or lever to connect a fixed number of contacts. They are also known as multi-pole switches, rotary drum switches, and selector switches. The 56SD30S-01PAJN rotary switch is an ideal component for applications where an intermediate number of selectable positions is required. In a wide variety of uses ranging from motor control to avionics applications, this versatile switch provides the necessary tasks and is a reliable component.

The 56SD30S-01PAJN is a miniature 4-pole, single-throw switch with 30 possible positions and is rated at 12 amps max @ 125 Vac or 28Vdc carrying current. The switch is available with toggle or bat-handle; the bat-handle version allows for easy operation and up to 180 degree turn of the handle. The switch does not require additional hardware for mounting and is designed to be mounted into 15.8 mm diameter round cut-outs. This switch is available with terminals that accept screw, quick-connect spade, can also be obtained PCB-mounted.

The working principle of the 56SD30S-01PAJN rotary switch is based on its electrical contacts themselves, consisting of a pair of conductors separated by an insulator. When the switch handle is in the off position, the two conductors remain separated and the switch is thus open. When the handle is rotated to the required position, the conductors are slid together and form a connection, thus closing the circuit. The amount of fixed positions the switch can be set to is determined by the length of the switch handle and the number of contacts within the switch.

The 56SD30S-01PAJN rotary switch is designed for a wide range of applications such as controlling light levels, equipment speeds, and motor speeds. It is also suitable for multiple audio-related functions such as selecting frequency bands, gain control, and tone control. This switch’s wide rotation range and high electrical current makes it ideal for applications such as audio mixers, stereo systems, audio amplifiers, and loudspeaker systems. For avionics applications such as aircraft navigation and control, the switch provides reliable and accurate control.

In summary, the 56SD30S-01PAJN rotary switch is a reliable, low-cost, and easy to use switch that provides many possibilities in various application fields. This switch is cost efficient, robust, and provides various features such as a wide rotating range and multiple handle styles. Its wide range of applications and selectable positions can be tailored to fit specific needs and make it a valuable component in motor control, audio, and avionics applications.
