Abstract

A structure of rotary switch sends out a control signal based on a rotation operation and includes: a socket, more than one signal output components, a trigger component, a rotary wheel, a positioning component, and a fastener, in which the trigger component and the fastener are separately installed on the two sides of the rotary wheel. The trigger component corresponds to the signal output components, and the positioning component corresponds to the fastener. The fastener is installed with positioning holes. The rotary wheel rotates in the socket in order to drive the trigger component and the positioning component so that the trigger component rotates and contacts the signal output components in order to output corresponding control signals. Furthermore, the positioning component sequentially passes through the positioning holes of the fastener so that the rotary wheel generates a cascade-type rotation.
