摘要

The keyboard has a number of sprung movable pushbutton tappets in guide-domes. The pushbutton tappets are connected to pushbutton caps which overlap the guide-domes. At least one pushbutton cap, whose pushbutton tappet is associated with one guide-dome is enlarged to cover two guide-domes. A pin-shaped guide element (10) in the space between the two guide-domes is fixed to the pushbutton cap (11) of the double pushbutton. The guide element is connected to both guide-domes and to an opposing element on the housing upper section between both guide-domes. ADVANTAGE - Prevents jamming of pushbutton even for off-centre operation of pushbutton cap.
