Non elastic pieces are sewn to an elastic band. When the band is stretched, the contacts touch!

Temple Flex Switch

A hard frame suspends flexible cloth with a metallic contact on one side and a non metallic contact on the other. A second contact is placed over the first contact so when teeth are grit, the users temple flexes, pushing the two contacts together. Simple right?
