    Abstract: A housing for an electrical device is proposed that contains electrical or electronic components and that is capable of being submersed in a liquid medium. A pressure-equalization element (2) is present on the housing (1), by means of Which compensation of the pressure inside the housing (1) with the outside pressure can be obtained. The outside pressure is delivered to the pressure-equalization element (2) via a submersible bulb (5) that is also submersed in the liquid medium, and the enclosed air volume of which has an active connection with the outside of the pressure-equalization element (2). The volume of air in the submersible bulb (5) is dimensioned so that it is greater than the volume of air to be tracked given a specified temperature decrease in the housing (1).
