A rocker arm includes an outer arm defining a stop aperture with a stop surface; an inner arm which selectively pivots relative to the outer arm; a latching mechanism which switches the rocker arm between a coupled state in which the inner arm is prevented from pivoting relative to the outer arm in a first direction and a decoupled state in which the inner arm pivots relative to the outer arm; a lost motion spring which biases the inner arm to pivot relative to the outer arm in a second direction which is opposite from the first direction; and a stop pin fixed to the inner arm and extending into the stop aperture such that the stop pin is circumferentially surrounded by the stop surface and such that the stop pin within the stop aperture limits the extent to which the inner arm pivots relative to the outer arm.
