Abstract
A thermostat comprises a first laminated metal plate and a second laminated metal plate in which a plurality of metal layers having different rates of expansion are laminated. The first laminated metal plate has a movable contact. The second laminated metal plate is disposed in such a position as to put the first laminated metal plate to the off and on positions. The first and second off temperatures, which put the movable contact in the off position by causing the first and second laminated metal plates to deform, and the first and second return temperatures, which return the movable contact from the off position to the on position, are set respectively at different temperatures.
