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.

Timer switch

An automatic timing control device case which is used for accommodating a timing control rotation shaft and a plurality of switches. A motor is disposed on the case for driving a gear set connected to the timing control rotation shaft to rotate, thereby controlling on or off of the switches through the timing control rotation shaft. The automatic timing control device case includes a body and a gear box. The body has an accommodation space for accommodating the timing control rotation shaft and the plurality of switches. The gear box is integrally formed in the body for accommodating the gear set. The gear box has at least one through-hole communicating the gear box and the accommodation space, such that the gear set is connected to and drives the timing control rotation shaft.

Automatic timing control device case

An electromechanical program timer provides at least a section with a slower timing speed besides a major timing speed. The timer includes a driving motor rotationally drives a driving shaft. A driving gear and an eccentric shaft are formed on the driving shaft for driving a cam disk through a main driven gear and via a pushing pawl to a driven ratchet respectively. The main driven gear includes at least a missing gear portion where the driving gear is free from driving the main driven gear, and the pushing pawl and the driven ratchet take place. The driving shaft engages and rotates the cam disk through the main driven gear in a major timing speed. While at the missing gear portion, the eccentric shaft oscillates the pushing pawl and drives the cam disk through the driven ratchet step by step in a reduced timing speed.
