Slim pushbutton unit (21), comprising a support base (23) and a button (24), mounted on the support base (23), provided for moving between an actuating position and a rest position. The button (24) has a body (28) hinge-mounted on the support base (23) through a linkage comprising a bridge section (29) of the aforementioned body (28). The crosspiece of the bridge (29) constitutes the pin (31) of the hinge-mounting and has an appendage (32). The support base (23) comprises a protruding slug (34) that defines cylindrical surfaces (36, 37) and a channel (38), respectively coupled with the pin (31) and with the appendage (32) for rotational guidance and axial contrast of the button (24), substantially without any play. <IMAGE>
