BTSI with lead frame switch

A releasable shifter lock for use in automotive brake-shift interlock systems comprising:

• a housing having an interior surface;
• a blocker member mounted within the housing for movement between a first position which locks an associated shifter and a second position which releases an associated shifter;
• a solenoid comprising an actuator rod which retracts from the solenoid into the housing when the solenoid is energized;
• a lead frame comprising flat stock conductors mounted on said interior surface;
• and
• a switch including a sliding contact member mounted on said blocker member and engaging the lead frame conductors for controlling the energization and deenergization of the solenoid according to the position of the blocker member.

In a shifter lock for use in an automotive brake-shift interlock system:

• a housing having an integral internal slideway;
• a blocker bar movable within the slideway from a rest position and having an electrical contact disposed thereon;
• a solenoid having an armature biased into interfering relationship with the blocker bar;
• and
• a lead frame mounted to and internally of the housing to control energization of the solenoid, the lead frame, together with the electrical contact on the bar, defining a switch which deenergizes the solenoid when the bar is moved from the rest position.
