Two-Hand Controls 4
Two-Hand Controls 4 : Two-hand controls are a set of switches that are actuated to start a machine cycle. Certain designs required constant actuation throughout the machine cycle. The switches must be mounted far enough apart to insure that one arm cannot actuate both switches. Normally anti-tiedown circuitry is incorporated which insures that one switch cannot be tied or taped down and the machine operated with one control. The control circuitry requires that each switch open and close on each cycle. The control circuit must be control reliable
