A solenoid assembly (10; 110; 210; 310) is provided in which electrical energy is supplied to a coil (16; 116; 216) through a post (28A; 128A; 228A) that extends through an armature. The solenoid assembly includes a coil assembly (18; 118; 218) having a coil (16; 116; 216), with a pole piece (22; 122; 222; 322) and an armature (12; 112; 212; 312) at least partially surrounding the coil. The armature is configured to translate relative to the pole piece when the coil is energized. The coil assembly has a bobbin (26; 126; 226) at least partially surrounding the coil and a first post (28A; 128A; 228A) that extends from the bobbin. Electrical current is supplied to the coil through the first post. The armature is configured so that the first post extends through the armature. A feature (80; 180; 280) is configured to prevent the armature from contacting the first post when the armature translates. |
