摘要： A hand dryer timer assembly including a plate with a timer motor mounted on one side of the plate and a switch mounted on an opposite side of the plate. The switch is in electrical communication with, and controls the operation of, the timer motor. A cam is mounted on a drive shaft of the timer motor such that the cam rotates with the drive shaft and also slides longitudinally over the drive shaft. The cam extends through an opening in the plate and has a flange at one end located adjacent the one side of the plate to prevent the one end of the cam from moving past the one side of the plate. The cam further has a cam lobe located on the opposite side of the plate adjacent an actuating arm of the switch. A biasing element is located between the timer motor and the cam and biases the cam to a first position aligning the cam lobe with the actuating arm of the switch.
