Claim 11:
12. A rocker arm, comprising:
a cam side arm comprising:
a bearing surface, a cam-side pivot extension, and a plunger seat arranged in a triangular configuration, and a centered longitudinal force transfer axis along which the bearing surface is configured to transfer an actuation force to the plunger seat; and

a valve side arm comprising:
a rocker shaft bore configured to receive a rocker shaft;
a valve side pivot extension pivotally connected to the cam-side pivot extension;
an electromagnetic capsule including a hollow capsule body comprising:
a plunger configured to receive the actuation force from the plunger seat;
a spring seat configured to receive the plunger and to reciprocate in the hollow capsule body, and
an electromagnetic latch comprising a solenoid-actuated pin configured to selectively engage a pin recess formed in the plunger so as to switch the plunger between a latched condition and an unlatched condition;

a capsule mount comprising:
a capsule bore configured to receive the electromagnetic capsule, and an end face at an inner end of the capsule bore;
a lost motion spring biased between the end face and the spring seat, and
a centered longitudinal lost motion axis along which the plunger selectively acts on the spring seat so as to collapse the lost motion spring, the centered longitudinal lost motion axis being offset from the centered longitudinal force transfer axis such that the plunger receives the actuation force from the plunger seat at an offset from the centered longitudinal lost motion axis; and

an arm extension extending from the rocker shaft, the arm extension configured to be coupled to a valve arrangement.
