ABSTRACT:
A switch (13) is provided with a common actuator (38) which is movable through successive discrete positions (47) for effecting successive circuit closures between a common circuit portion (21) and a selectable one of a plurality of conductors (20). In any selected position of the actuator, a deformation of the actuator, without changing its selected position, effects a further discrete circuit closure (58, 57) to indicate that an actuator position has been selected. These closures are advantageously utilized in a telephone station set environment to control a dialed digit display and to enable registration of a sequence of dialed digits for subsequent transmission.
