Rotary Switches

Rotary switches are electronic switches that are activated by rotating a dial or knob. They are commonly used in a variety of applications, such as audio equipment, industrial control systems, and consumer electronics.

Rotary switches typically consist of a housing, a dial or knob, and a set of electrical contacts. When the dial or knob is rotated, it completes a circuit between the contacts, allowing electrical current to flow through the switch. Some rotary switches also include detents or stops that provide tactile feedback as the dial is rotated.

Rotary switches come in different configurations, including single-pole, double-pole, and multi-pole switches. They also come in different contact arrangements, such as make-before-break, break-before-make, and center-off switches.

Rotary switches offer several advantages over other types of switches. They provide a simple and intuitive means of controlling circuits, and they offer tactile feedback that can help to ensure reliable operation. They are also highly durable and can withstand frequent use and harsh environments.
