A switchable lever for a valve drive of an internal combustion engine, which has an elongated housing with two side walls. A crossbar for a gas-exchange valve system and another end of the housing has a hearing for pivotable support of the crossbar. An axle is held nondisplaceably in the side walls. An axially fixed low-lift cam roller is seated centrally on the axle and is flanked on both sides by a high-lift cam roller. The high-lift cam rollers are displaceable: (a) into a first position, away from each other, to toward the side walls such that contact of one high-lift cam per high-lift cam roller is possible, and (b) into a second position, toward each other, such that they are located outside an engagement region of the high-lift cams, and as a result of which contact of a low-lift or zero-lift cam with the low-lift cam roller is possible.
