| Definition: | a contactor, the moving elements of which are prevented by means of a latching arrangement from returning to the position of rest when the operating means are de-energized
NOTE 1 – The latching, and the release of the latching, may be mechanical, electromagnetic, pneumatic, etc.
NOTE 2 – Because of the latching, the latched contactor actually acquires a second position of rest and, according to the definition of a contactor it is not, strictly speaking, a contactor. However, since the latched contactor in both its utilization and its design is more closely related to contactors in general than to any other classification of switching device, it is considered proper to require that it complies with the specifications for contactors wherever they are appropriate.
