摘要： A timer includes a case, a shaft, a cam wheel, a drive mechanism, and a plurality of switch blades disposed within the case. The shaft is rotatably and reciprocally movably disposed in the case. The cam wheel is pivoted on the shaft and rotates together with the shaft when setting, or rotates independently by the drive mechanism. The cam wheel includes a plurality of cam tracks on one side surface thereof and a plurality of ratchets and grooves on a circular rim thereof. The drive mechanism contacts the ratchets to drive the cam wheel to rotate relative to the shaft. The switch blades respectively contact the cam tracks of the cam wheel, and correspondingly generate an electrical connection/disconnection. When the shaft moves to the setting position and the cam wheel being rotated by the user, a flexible element touches the grooves formed on the circular rim results a tactile feedback.
