Abstract
A liquid and gas impenetrable switch, especially for electrical surgical instruments, has two pairs of contacts spaced from one another. The movable contact element of each pair is arranged between the associated fixed contact element and a diaphragm. With elastic deformation, the diaphragm and movable contacts can be moved by the switch operating force into contact with the fixed contact elements. The diaphragm covers the movable contact elements and is supported by a rocker.
