FIELD: technology for testing functional capability of electronic switch.
SUBSTANCE: switching device contains switch being tested with first clamp and second clamp, and also control clamp for controlling resistance between first clamp and second clamp, resistor, device for feeding measurement current through resistor to first clamp of switch being tested. Control clamp and first clamp of switch being tested are electrically connected. Switching device contains device for registration of voltage change resulting from current between control output and second output of switch being tested. Voltage points at serviceability of switch being tested.
EFFECT: due to usage of switching device, greater number of possible occurring errors of switch being tested is detected when compared to conventional switching device.
