ABSTRACT:
A solenoid-operated latch for a linearly movable shaft such as a shift lever shaft of a vehicle transmission includes an L-shaped armature that forms a latch plate and a magnetic arm. The shaft extends along the solenoid axis and through a clearance hole in the latch plate. Energization of the solenoid draws the magnetic arm toward a planar pole piece at one end of the solenoid winding. The latch plate swings from a position normal to the shaft axis to a tilted condition acutely angled to the shaft axis so that edge areas of the clearance hole grip the shaft surface.
