A rotary switch includes a base seat having a shaft, a round track portion, a resilient element, a rotary element pivotally mounted onto the shaft, a contact element, a plurality of conductive terminals, a cover, and a circuit module. The base seat has a restraining portion where the resilient element is disposed therein. The rotary element is formed with an interference teeth portion. The contact element and the interference teeth portion are capable of rotating in conjunction with the rotary element whereby enabling a plurality of contact arms of the contact element to electrically contact the plurality of conductive terminals. The resilient element is deformed and stretching backwards in conjunction with rotation of the rotary element, and returns to an original position to engage with the interference teeth portion when the rotary element rotates in position. |

1. A rotary switch mechanism, comprising:
a base seat comprising a shaft, at least a restraining portion, and a round track portion, the shaft and the restraining portion respectively extending upwards out of a surface of the base seat and spaced apart from each other, and the round track portion disposed around the shaft between the shaft and the restraining portion; a rotary element pivotally mounted onto the shaft, an interference teeth portion formed on a periphery of the rotary element above the round track portion; a resilient element of which one end is connected to the restraining portion, and another end of the resilient element extending out of the restraining portion and resiliently engaging with the interference teeth portion; a cover covering the interference teeth portion and the restraining portion; a plurality of conductive terminals disposed under and around the base seat, one end of each of the conductive terminals extending out of the base seat to form a soldering portion; a contact element mounted to a bottom of the rotary element between the plurality of conductive terminals and the base seat, the contact element comprising a plurality of contact arms for electrically connecting the plurality of conductive terminals; and a circuit module disposed below the base seat and electrically connected with the plurality of conductive terminals where the plurality of conductive terminals penetrate the circuit module, the circuit module at least comprising a base plate and multiple pins, and the multiple pins extending out of the base plate so as to electrically contact a circuit board; wherein the rotary element is pivotally rotatable about the shaft along the round track portion, and the contact element and the interference teeth portion being capable of rotating in conjunction with the rotary element whereby enabling the plurality of contact arms of the contact element to electrically contact the plurality of conductive terminals along the round track portion so as to generate electrical signals which are then being transmitted to the circuit module for coding signals, the resilient element being deformed and stretching backwards in conjunction with rotation of the interference teeth portion, and the resilient element returns to an original position to engage with the interference teeth portion when the rotary element rotates in position. |
