摘要： An electric timer for measuring predetermined time intervals to which the timer can be manually set. The timer includes a motordriven main timing shaft equipped with an indicator hand moved by the shaft about a calibrated face subdivided into time intervals. The shaft is equipped with a knob to facilitate manual positioning of the hand at any selected time interval, and the timer is placed in operation by manual displacement of such knob, shaft, and hand from a zero time position into any time-measuring calibration. A light providing a visual indicator is included, and it is energized concurrently with the timer motor to provide indicia that the timer is in operation. A buzzer or other audible indicator is also included, and it becomes operative at a predetermine instant in any timing interval being measured to provide indicia that the timing cycle has been or is nearing completion. The timer is arranged so that both the visual and audible indicators are energized concurrently for a brief interval of predetermined duration, and all of the various states of the timer are generally responsive to and determined by the condition of a main control switch which is sequentially changed from a normal-run, to an alarm-run, and then to a non-run condition in accordance with predetermined angular position of the timing shaft during a timing cycle.
