I have an exterior lamp that is controlled by a standard switch and a 'timed-relay' (I push a button and light stays on for 3 minutes), I think those two are wired in parallel as if the lamp is on and I operate the relay button it clicks (so it has power). If I switch OFF the breaker and the switch is ON the led bulb, instead of staying dark, starts blinking, but if I switch the light on by the relay then I switch off the breaker, light stays off (in this situation if I flip on the switch, bulb stays dark). What can be?
PS: I'm in EU (230V), my earthing is TT, my breakers are double pole, my main breaker is RCD.
