Pontiac Coil also offers a latching option for their solenoids. Latching solenoids do not require power to be applied to the coil to hold the armature in the seated position. While in the seated position, the zero power holding force of the solenoids can be up to ten pounds. The result of this latching feature is that no power is consumed by the coil while in the seated position. This makes it ideally suited for battery or limited power source applications.
