Abstract
The unit transfer finger pressure onto a release mechanism. A piston (21) compresses the air inside a cylinder (6) whose interior is connected to the outside via an aperture (26) maintained closed during actuation. The cylinder is positioned directly on the release mechanism. The connection aperture has a channel (23) in the piston. The outer end of the piston is forked, and has two outlet apertures (26,27) positioned in the finger contact surface (28). The distance between the apertures is larger than the diameter of a child's thumb, when pressed flat, but smaller than the thumb of an adult.
