what is a 2 pole rotary switch - IOT Wiring Diagram

A two-pole rotary switch is an electrical appliance used to route power from one device to another. This type of switch is typically used in tasks that require the selection and control of multiple circuits or devices, such as in electronic music equipment. The main components of a two-pole rotary switch are an actuating knob, contact points, and a series of cams.

The knob is externally visible and usually contains a mechanical identifier to show the user what circuits are currently active. Underneath the knob is a series of contacts which are used to direct the flow of current between two or more devices. A cam is used to hold each contact in place whenever the knob is turned. The cam can be configured to alternate the contact position in either a clockwise or counter-clockwise direction.

Two-pole rotary switches can vary in design and complexity, depending on the application. Digital switches use microprocessors to enable multiple settings in the same switch. Other versions may combine two switches in one package for advanced functionality. Robust construction is essential to maintain capacitance ratings and avoid connections becoming unreliable over time. Careful consideration must be given to the environment where the switch is to be used, ensuring it is compatible with the relevant safety certifications.
