Abstract: A non-contact proximity switch having a first part and a second part which do not need to be in physical contact to detect proximity of the first and second parts. The first part is arranged to be connected to a reset circuit including an indicator light and a reset switch having a reset button. The first part includes a reset mechanism for machine safety, and the reset mechanism includes a signal generator and a signal detector. The reset mechanism is arranged to, upon indication that a reset is required, generate a signal so as to switch-on said indicator light, and the reset mechanism is further arranged to detect when the state of a connected reset switch corresponds to a state where the reset button is being pressed.
