What is a rotary switch?

Rotary Switch is a switch that switches the circuit connection status by rotating operation.

Rotary Switch usually consists of multiple contacts and a rotating shaft, which can establish or disconnect circuit connections between different contacts through the rotating shaft.

How does rotary switch work?

The working principle of Rotary Switch is based on mechanical contact, changing the connection state between contacts through the position of the rotating axis.

When the axis of rotation is aligned with a specific contact, current can flow between the contacts, completing a circuit connection.

Through the rotation of the rotating shaft, different contact combinations can be switched to realize circuit connections with different functions.
