Valvetrain power transfer module with shortened leaf-spring contact

A valvetrain for an internal combustion engine of a type that has a combustion chamber and a moveable valve having a seat formed in the combustion chamber, comprising:

• a camshaft;
• a pivot including a dome portion;
• a rocker arm assembly mounted on the pivot and comprising a rocker arm having a gothic, a cam follower configured to engage a cam mounted on the camshaft as the camshaft rotates, and two contact pins protruding to opposite sides of the rocker arm assembly;
• an electromagnetic latch assembly comprising a latch pin and an electromagnet powered through at least one of the contact pins, wherein the electromagnet is operable to move the latch pin between a first latch pin position and a second latch pin position;
• a power transfer module comprising a framework;
• and
• two contact pads each contacting a respective one of the contact pins and having inward facing rolls that form inward bends to facilitate retention of the rocker arm assembly on the pivot,
• wherein the contact pads are deformed outward to allow the contact pins to move past the inward bends when the rocker arm assembly is pushed downward until the gothic of the rocker arm contacts the dome portion of the pivot.
