Abstract

A thermally responsive switch (1) comprises first and second electrical terminals (12, 24; 25), a thermally responsive switch actuator (6), and a housing comprising a first metal plate (4) in electrical contact with the first electrical terminal (24; 25), a second metal plate (11, 3; 22) in electrical contact with the second electrical terminal (12), and insulating material (9) disposed between the first and second metal plates (4, 11, 13; 22).
