A switchable tappet for directly transmitting a cam lift onto a tappet push rod, includes a housing having a push rod distal end which is formed with a ramp surface for contact by a cam. An inner element is placed in a recess of thehousing and has a push rod proximal end formed with an abutment for the push rod. Secured to the push rod proximal end of the inner element is an attachment to extend the inner element beyond the recess of the housing, wherein the attachment has a housing-distal end formed with a shoulder. A helical compression spring extends between the shoulder of the attachment and a rim of the housing for urging the inner element in a direction of the push rod, and conically expands, at least partly, in the direction of the push rod and is wrapped around the attachment of complementary conical configuration.
