The protective cap is made of flexible plastic material. The baffle is curved in a hemispherical shape outwards against an actuating direction (8) of the push button. The baffle is provided for producing a pre-tensioning force acting on the protective cap such that the cap lies on a surface of the baffle in an air sealed manner in a non-actuated condition of the push button under pre-stress.
