The invention proposes a switching element (1) for a valve train of an internal combustion engine, said switching element comprising an outer element (2) and an inner element (4) that is arranged for axial displacement in a bore (3) of the outer element (2), each of the outer element (2) and the inner element (4) comprising at least one reception (12, 9) aligned to each other in an axially distant relative position which is achieved through a lost motion spring (8), at least one piston (10) being arranged in at least one of the receptions (12, 9) for sliding toward the other of the receptions (12, 9) to couple the inner element (4) to the outer element (2) in said relative position, and a high-position stop for defining said relative position being arranged between the inner element (4) and the outer element (2). The inventive high-position stop is made as a separate element (16) such as a disk or a circlip with a variable thickness that is fixed on one of the outer element (2) and the inner element (4) and cooperates with a stop surface of the other of the outer element (2) and the inner element (4). These extremely simple fabrication measures enable an alignment of the receptions (9, 12) for achieving coupling.
