Abstract

The switching element has at least one pressure chamber which is at least partly provided with a membrane (4) enabling connection of a stimulation contact element (5) to make contact with a tapping contact element (6). The stimulation contact element and/or tapping contact element can be moved out of a contact plane to make a common contact .
