Abstract

A switching roller finger follower, including: a housing with a first wall with a first opening, a second wall with a second opening, and an interior space at least partially formed by the walls; first and second outer arms; and a locking pin disposed in the openings and including a longitudinal axis, a body, and first and second protrusions extending radially outward from the body, formed of a same piece of material as the body, and at least one of which is located within the space. A respective portion of at least one of the first or second protrusions is aligned with the first or second wall in a direction parallel to the first longitudinal axis. The locking pin is displaceable such that: in a locked mode, the locking pin blocks pivoting of the arms; and in an unlocked mode, the locking pin is free of contact with the arms.
