Rocker systems with cylinder deactivation and selective valve lift capabilities

A rocker system for an internal combustion engine, the rocker system comprising:

• at least one input rocker lever rotatable about an engine component in response to motion received from at least one camshaft lobe of a camshaft;
• at least one output rocker lever rotatable about the engine component, wherein the at least one output rocker lever is configured to control opening and closing of at least one exhaust valve or at least one intake valve associated with a cylinder of the internal combustion engine;
• at least one valve lift switch operable to:
• connect the at least one input rocker lever and the at least one output rocker lever to one another for transferring motion from the at least one camshaft lobe to the at least one exhaust valve or the at least one intake valve;
• disconnect the at least one input rocker lever and the at least one output rocker lever from one another;
• a biasing mechanism in contact with the at least one input rocker lever and the at least one output rocker lever and configured to bias the at least one input rocker lever into direct or indirect contact with the at least one camshaft lobe;
• and
• a first stop member and a second stop member configured to contact the first stop member to prevent over-rotation of the at least one input rocker lever under the bias of the biasing mechanism.
