Abstract
A manual transmission shifter and ignition interlock is provided for a vehicle having a manual transmission operated by a shift lever (20). A bi-stable solenoid (86) is movable between positions blocking and unblocking movement of the vehicle ignition (78) to OFF. Another bi-stable solenoid (66) has an output arm (68) which operates a control linkage (54) and raise and lower a locking lever (48) to engage and disengage the locking level from a locking probe (34) on the shift lever to lock and unlock shift lever (20) when in REVERSE. The solenoids (66, 86) are controlled by a controller (74) that is provided with high and low current inputs from branch circuits (90, 92) that include control switches (94, 96) operated by ignition position. The controller (74) causes solenoid (66) to extend the control linkage (54) when the shift lever (20) is moved to REVERSE, and the ignition (78) is moved to ACCESSORY. This closes a switch (96), causing the controller (74) to retract the ignition solenoid (86) and enable movement to OFF for key removal.
