<p>The touch switch system for an industrial seqing machine to select and activate the various electronic control circuits, has strip contacts separated from each other to be bridged by a hand or finger touch. They are arranged lengthwise, so that they lie on the movement pat of the operator's hands in moving the fabric, to form switching zones. The strip contacts have a length which is a multiple of the remaining dimensions of the switch. The design gives a switch system operated by finger touch located where the hands are placed in working, so that the rapid operation of the electronic circuitry is exploited.</p> |
