A cold station thermal switch at the end of a cold finger in cooperation h the detector on an inner dewar wherein the thermal switch opens at the cool down cryogenic temperature to prevent vibrations from the cooler system from being transmitted to the detector. The thermal switch has an outer bellows fitted around the end of the last stage of the cooler which extends close to but not in contact with the detector and an inner bellows having a metallic bumper on the end thereof in contact with the detector until cool down to the operating cryogenic temperature at which time contraction of the inner bellows disconnects the metallic bumper from the detector.
