Abstract
A key for intermittently electrically contacting at least two conductors located on a circuit board with an electrically conducting contact element includes at least one base that is disposed on the circuit board and a key which encompasses the contact element and is movable relative to the circuit board and the base. The key is connected to the base by at least one movable membrane. The base and the membrane are made of an insulating elastic material. The key additionally includes at least one soldering leg of which the first end is positively inserted in to the base while the second end, the soldering zone, is used for fastening the key to the circuit board.
