Abstract
A vehicle transmission shifter in which a locking member is movable along a line in opposite directions to a locked position or unlocked position. A mechanical advantage means, preferably a toggle joint, is connected to one end of the locking member for either restraining or moving the locking member in response to the energization of an electrical coil of an electrical module which actuates an armature, or so-called module actuator, in a direction orthogonal to the toggle joint. The module actuator is biased to substantially align the axes of the toggle joint in which position the locking member is in locked position restrained from movement. When the brake of the vehicle is applied, the coil is energized and the module actuator is moved by the energization of the coil to break the knee of the toggle joint to unlock the locking member.
