Abstract (en)
[origin: EP2278604A1] The switch has an intermediate wall (42) designed as a part of a hollow metal casting body (40) that contains exhaust and suction openings (47, 48). An intermediate volume (44) is arranged between compression and exhaust regions (52, 43) and separated from the exhaust region by the wall. A piston-cylinder-compression device (50) has a piston (51) fastened at a front side of the body, where the piston axially limits the volume. A capacity of the volume defined by axial distance of the volume from the piston is larger than capacity of the compression region in a switch-on position of the switch.
