ABSTRACT:
A first signal representative of the position of a movable member, such as a machine tool slide, is generated. A plurality of second signals each representative of one or more positions and one of a plurality of actuatable output switches is stored in an addressable memory. The first signal is compared with each of the plurality of second signals stored in the memory. Responsive to the comparison, the output switch represented by one of the plurality of second signals is actuated when the one or more positions represented by such one of the plurality of second signals coincides with the position represented by the first signal.
