Abstract
Abstract An arrangement for applying a signal to one of a plurality of lines has a series of contact switches. Actuation of any one of the switches causes a pulse sequence to be applied to one of a plurality of input lines. The pulse sequence is also applied to a counter which counts until the counter output corresponds to the energized input line. The binary counter output is converted to decimal form and the decimal output energizes an output line corresponding to the energized input line.

Total Claims: 17
Claim 1
Independent Claim
176 words
Arrangement for selectively applying a control signal to one of a plurality of output lines, comprising, in combination, electronic step switch means having a step switch input and a plurality of step switch outputs, each connected to one of said output lines, for furnishing said control signal in sequence on said output lines in response to signals applied at said step switch input; a plurality of input lines each corresponding to one of said output lines; a plurality of pulse generator means each having an output connected to a corresponding one of said input lines, for furnishing a pulse sequence to said corresponding one of said input lines upon external activation, whereby external activation of one of said pulse generator means creates an energized input line; and circuit means connecting said input lines to said step switch input in such a manner that said sequence of pulses is applied to said step switch input until said step switch output furnishes said control signal to the one of said output lines corresponding to said energized input lines.
