Abstract
An apparatus and method test an electric circuit. During the testing of the switches connected in series with the ignition pellet, the maximum current flowing through the respective switch to be tested is limited to a value that is insufficient for igniting the ignition pellet even in the event of a leak occurring. This current limiting is preferably achieved by reducing the switch gate voltage while the switch test is being accomplished.
