<p>The push button (12) has a coupling end piece (26) coupled with a distribution rod (22) e.g. valve rod, and a rod activation unit (28) that partially moves with respect to a body (24) under an effect of force exerted by a user. Transmission units (30) are moved between an active position, in which the movement of the activation unit allows product distribution, and an inactive position in which the movement of the activation unit does not cause the product distribution. The transmission units transmit the force to the rod, and are connected to the coupling end piece.</p> |
