Microcomputer-controlled programmable time switch

摘要

A microcomputer-controlled programmable time switch has a display for the acutal time and other functions. The other functions are obtained through easily understood legends, with keys for each individual function and with keys for the input, indication and erasure of time- dependent data and for the actuating of the switch independently of the time. If the sequence of operation is not arbitrary, the microcomputer guides an operator through the operating sequence by flashing the indicator lights required for the data readout or data input.
