Motor Start-Stop Stations

Does not matter how many stations, the stop buttons are series and the start are paralleled, as in two locations.

  1. The momentary start switch closes, then when released opens.
  2. The M coil energizes, closing contact AUX and the line to load contacts of the equipment.
  3. The AUX contact or Interlock, maintains power to the M coil until power is interrupted.
