A switchable roller finger follower is provided having an inner lever and two separate outer arms mounted at one end to a swing pivot axle that extends through the inner lever. A roller is mounted in the inner lever. The outer arms extend longitudinally along sides of the inner lever and include high lift cam contact surfaces. The inner lever includes a compression spring support extending out from each of the sides. The outer arms each include a corresponding spring support facing the respective spring support of the inner lever. A compression spring is located on each of the sides of the inner lever between the corresponding spring supports. A coupling arrangement is located between the inner lever and the outer arms which in a locked position, locks the outer arms in position on the inner lever, and in an unlocked position, allows the outer arms to pivot.
