ABSTRACT:
In an electronic timepiece the digital display of time functions is corrected by the manipulation of a multi-contact rotary switch. Rotation of the switch in one direction corrects one displayed function, e.g., hours and minutes, and rotation of the switch in the other direction corrects another displayed function, e.g., day and date. The rate of display correction is responsive to the rate of switch rotation. Rotational direction is electronically determined by detecting which contact in the rotary switch is the first to close. Rate of switch rotation is determined by measuring the time required in cyclic actuation of the rotary switch contacts.
