Switching rocker arm

An internal combustion engine, comprising:

• a lash adjuster mounted to an engine block;
• a cylinder valve configured to selectively open and close an exhaust or intake passage;
• a rocker arm assembly coupled to the lash adjuster at a first end and engaged with the cylinder valve at a second end opposite the first end, the rocker arm assembly comprising:
• an outer arm having a first outer side arm and a second outer side arm, each of the first and second outer side arms having a high lift lobe contacting surface,
• an inner arm disposed between the first and second outer side arms and pivotably secured to the outer arm, the inner arm having a low lift lobe contacting surface, and
• a latch assembly including a latch pin having an orientation pin receiving recess, a sleeve engaging the latch pin and having an orientation pin opening, and an orientation pin extending through the orientation pin opening into the orientation pin receiving recess, the orientation pin having a substantially cylindrical first wall and a substantially cylindrical second wall,
• wherein the latch assembly is selectively movable between a first configuration and a second configuration, the latch assembly configured to:
• (i) engage the inner arm with the outer arm such that the outer arm rotates with the inner arm in the first configuration, and (ii) disengage the inner arm from the outer arm such that the outer arm rotates independently from the inner arm in the second configuration;
• and
• a cam having a low lift lobe and two high lift lobes, each of the low and high lift lobes including an actuating portion and a non-actuating portion, the cam rotating during operation of the internal combustion engine such that the actuating portions interact with the rocker arm assembly to rotate at least one of the inner and outer arms.

• wherein the non-actuating portion of the second lobe is in a spaced relation from the second lobe contacting surface in a non-actuating condition and wherein the actuating portion of the first lobe of the cam is offset from the first lobe contacting surface in an actuating condition.
