Abstract
A board of electrical insulating material has power conductors mounted on one side and work circuits mounted on the other side. A power source to actuate the work circuits is connected to the power conductors in a set sequence. Holes are provided through the board to receive conductive pins to electrically connect power conductors to work circuits to actuate each selected work circuit at a predetermined point in the set sequence.
Claims6
A control system, including,
- a plurality of first conductors mounted on a support with each conductor having a section extended parallel to the sections of the remaining conductors,
- a plurality of second conductors mounted on the support with each conductor having a section extended parallel to the sections of the remaining conductors and a constant distance from all sections of the first conductors,
- a plurality of third conductors mounted on the support with each conductor having a section extended parallel to the sections of the remaining conductors and a constant distance from all sections of the first conductors,
- a multiple-position switch mounted on the support with each of its contactors electrically connected to one of the first conductors,
- an advance mechanism including a switch arm element for cycling the switch to each of its contactors,
- a source of electrical power connected to the switch arm element,
- a first work circuit connected to each of the second conductors,
- a second work circuit connected between each of the third conductors and the advance mechanism of the multiple-position switch and including a manually adjustable time delay system which determines time dwell of the switch at that one of the first conductors connected to one of the third conductors,
- a first conductive element which is manually positioned through the support to electrically connect one of the first conductor sections with one of the second conductor sections,
- and a second conductive element which is manually positioned through the support to electrically connected one of the first conductor sections with one of the third conductor sections.
