Hi Xperiencess, this component is a flow switch, when putting voltage has given a firecracker, normal, this is a two-position switch, NC and NO (normal closed and normal open) Between black and red NC cable, between black and orange NO; measure black with orange with a tester and do not measure, if you measure it black with red it will give you the continuity tester. On one side it has a screw to adjust the sensitivity, if you turn on schedule it increases the sensitivity, on the contrary it decreases. You must have tried it in the following way, you connect the black to phase, the orange to lamp the other lamp cable to neutral, when passing pressure the sensor closes the contact and turns on the lamp and on the contrary if you want it to turn off. It means that this is a switch. Possibly it is broken now, see if you can get it changed for another.
