Abstract

The present disclosure refers to systems (102, 103, 104, 105, 106, 107), devices, and corresponding methods for detecting a condition of a switching element (510) in a safety switch (500), including obtaining a signal indicative of an impedance of a safety switch (500) between an input port (712) and an output port (714) thereof, controlling the gate port (511) of the safety switch (500) to switch the switching element (510) between a closed state and an open state, comparing the impedance of the safety switch (500) in the closed state with the impedance of the safety switch (500) in the open state, and determining a condition of the switching element (510) based on the comparison.
