Abstract
A switch device includes a switch to be tested with a first terminal and a second terminal as well as a control terminal for controlling a resistance between the first terminal and the second terminal. Furthermore, the switch device includes a resistor as well as means for providing a measuring current across the resistor into the first terminal of the switch to be tested, wherein the control terminal and the first terminal of the switch to be tested are coupled in electrically conductive manner. Furthermore, the switch device includes means for sensing a voltage present due to the measuring current between the control terminal and the second terminal of the switch to be tested, wherein the voltage refers to an operability of the switch to be tested. With the switch device, in particular a greater number of potentially occurring errors of the switch to be tested can be detected as opposed to conventional switch devices.
