its very common this fault and like tel Say why always the neutral terminal they are a weak point carrying a large load , im the same as tel outside switch when ever i can never had a problem with the scolmore switches , i have a tendancy of torquing them up these days around 2.3nm only thing i can think is temperature changes that loosen the connections hence it burns out do like the crabtree ones but they look so big and can be a pain to wire
