Abstract

In the case of a switching element, a pressure-compensation element (20) is inserted in the base body (10) of the terminal strip (11) in a recess so that a pressure compensation is possible between the interior of the housing (17) and the outer atmosphere. By means of this special arrangement of the pressure-compensation element (20) in the terminal strip (11) it is possible to test the functional capability of the pressure-compensation elements in the installed state in a simple way without additional testing processes.
