A switchable mount includes a partition wall which partitions a working chamber from a compensating chamber. A first diaphragm is arranged in the partition wall so as to be deflectable in the longitudinal direction of the mount. A switching actuator controls the diaphragm and, in a first state thereof, the diaphragm is fixed in a rest position and, in a second state thereof, the diaphragm is released to move in the longitudinal direction of the mount. A second diaphragm is arranged in the partition wall and is deflected in the longitudinal direction of the mount to influence the volume of the working chamber. An air chamber is arranged between the first diaphragm and the second diaphragm. In the first state of the actuator, the air chamber is closed off air-tight to the atmosphere and, in the second current-conducting state of the actuator, is connected to the atmosphere.
