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).

Abstract: In a known safety device, a relative position of an adjuster element with respect to a driver can be monitored, and a current path required for this purpose can be checked. To this end, two wipers must lift away from two wiper paths, depending on the position of the driver and adjuster element. Because of this liftoff, early wear of the wiper paths and considerable shifting of the switch point must be expected. In the safety device according to the invention, two switch lugs are provided on the adjuster element and a cam is provided on a base. This has the advantage above all of producing a safety device that is simple to manufacture and is durable. The safety device is especially suitable for power control systems for motor vehicles.
