Rotary SwitchesRotary switches are a type of switch that is activated by rotating a dial or knob. These switches are commonly used in a wide range of applications, including audio and video equipment, instrumentation, and control panels. Rotary switches are often preferred over other types of switches because they allow the user to easily select from a range of different settings or positions. Rotary switches typically include a rotating actuator, such as a dial or knob, that is mechanically linked to one or more electrical contacts. When the actuator is rotated, the contacts are opened or closed, completing or interrupting the circuit. There are many different types of rotary switches, including single-pole, double-pole, and multi-pole switches, which are designed for different applications and circuit configurations.
