Contactor, Latching
A contactor that maintains its position after power has been removed from the coil. Typically, the contacts are held closed through the use of a permanent magnet, and held open through the use of a spring. To close the contacts, a short pulse is applied to the coil. To open the contacts, a short pulse of opposite polarity is applied to the coil. The duration of the pulse can be found on the data sheet.
