Leaf spring sliding contact for electrically actuated rocker arm assembly

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

• a rocker arm assembly comprising a rocker arm and a cam follower configured to engage a cam mounted on the camshaft as the camshaft rotates;
• and
• an electrical circuit comprising an electrical device mounted to the rocker arm;
• wherein the electrical circuit includes a first electrical connection made by abutment between a first part and a second part, which are two distinct parts;
• the valvetrain is operative to slide the second part over the first part in response to actuation of the rocker arm assembly through the cam follower;
• and
• the first part is a contact pad having resiliency that biases the contact pad against the second part.
