ABSTRACT:
Electrically powered apparatus is provided with a remote primary control station from which energization of the apparatus is usually controlled, and a secondary control station, such as a jog control station, which is remote from the primary control station and close to the apparatus, from which energization of the apparatus may also be controlled. A single manual push button start control module may be mounted at either station, so that when the module is at the secondary station there is no start button at the primary station. A holding circuit provides for extended energization of the apparatus when the push button is momentarily depressed at the primary station, and there is a stop button at the primary station; while the secondary station has no holding circuit. The holding circuit is disabled when the module is mounted at the secondary station, so the apparatus cannot be energized by mounting a second identical start control module at the primary station.
