Abstract
A cycle-select switching system for automatic appliances and the like of the type for selectively performing any one of a plurality of distinct operating cycles. The switching system comprises selection means having a plurality of outputs, each corresponding to one of the operating cycles, and a momentary contact switch for producing a control signal of variable time duration. The selection means is responsive to the control signal by sequentially advancing to the output defined by a selected time duration of the control signal and thereby initiating the operating cycle corresponding thereto.
Claims11
In a machine of the type having an electronic digital control system including a control logic circuit capable of carrying on a plurality of operating cycles, each cycle comprising a plurality of events performed by a number of machine devices, each of said operating cycles being selectable by energizing a corresponding cycle-select input of said control logic, the improved switching system for selecting any desired operating cycle in combination therewith comprising:
- a. generating means for producing a control signal;
- b. a momentary contact switch having an input connected to said control signal and having an output;
- and
- c. selection means having an input connected to said output of said momentary contact switch and having a plurality of outputs, each of said outputs of said selection means being connected to a corresponding cycle-select input, said outputs repeatedly energizing sequentially each of said cycle-select inputs for a predetermined period shorter than the duration of the corresponding operating cycle as long as said control signal remains connected to said input of said selection means through said momentary contact switch.
In a machine of the type having an electronic digital control system including a control logic circuit capable of carrying on a plurality of operating cycles, each cycle comprising a plurality of events performed by a number of machine devices, each of said operating cycles being selectable by energizing a corresponding cycle-select input to said control logic, the improved switching system for selecting a plurality of desired operating cycles in combination therewith comprising:
- a. generating means producing a plurality of control signals;
- b. a momentary contact switch for each of said control signals, each of said momentary contact switches having an input connected to its respective one of said control signals, and having an output;
- and
- c. selection means having a plurality of inputs, each of said inputs connected to a corresponding output of said momentary contact switch, said selection means having a plurality of sets of outputs, each of said outputs of each set being connected to a corresponding cycle-select input, said outputs of each set repeatedly energizing sequentially each of said corresponding cycle-select inputs for a predetermined period shorter than the duration of the corresponding operating cycle as long as said corresponding control signal remains connected to its respective input of said selection means through said corresponding momentary contact switch.
A cycle-select switching system comprising:
- a. generating means for producing a control signal;
- b. a momentary contact switch having an input connected to said control signal and having an output;
- and
- c. selection means having an input connected to said output of said momentary contact switch and having a plurality of outputs which are repeatedly energized sequentially as long as said control signals remains connected to said selection means through said momentary contact switch.
