A control device comprises a supporting housing (30), a controller switch (32) fixed to the housing (30), an expansible chamber actuator (34) supported by the housing (30) for actuating the switch (32), a capillary tube (36) joined to the actuator (34), and a vibration damper (40) for minimizing vibrational flexure of the capillary tube (36). The damper defines a first end (82) fixed to the housing (30), a second end (84) remote from the housing (30) and a passage (86) extending between the ends and closely surrounding the capillary tube (36).
