摘要： A magnetic latching solenoid assembly comprises a bobbin having a central aperture formed therethrough along a central axis and having a solenoid coil wrapped therearound, and a metal polepiece secured at least partially within the bobbin. An at least partially metal armature is slidably movable within the central aperture. The polepiece includes a depression formed therein with a first flat formed at the bottom of the depression. The depression has a first wall formed at a first angle with respect to the central axis. The armature has a protruding portion for cooperation with the depression, the protruding portion having a second flat formed thereon for metal-to-metal engagement with the first flat, and having a second wall formed at a second angle greater than the first angle so that the first and second walls do not contact each other when the first and second flats are in contact.
