Is there polarity on the sensors which must be followed when you reinstall new ones?

I just replaced the front pads and rotors and all hardware including new sensors and my brake wear light is on. It was NOT on prior to the work. When I inserted the sensor into the pad, I didin't really hear a "click" to lock it in. does that matter? It is still seated in the hole. Perhaps I have bad sensors ( I highly doubt it). Probably user error on my part.
