Solenoid Fundamentals: Latching Solenoids
See how a latching solenoid operates without constantly drawing electrical current.

Rather than constantly drawing electrical current, a latching solenoid uses only a short pulse of power to move the armature and draws no current to maintain position. Depending on the design, the armature is held in the latched position by a permanent magnet or residual magnetism. Watch to learn more.
