Thermostat with bulging portion to prevent contact of a resilient plate to housing

摘要

A thermostat, having a seal structure, prevents contact of a resilient plate with an inner side of the housing, even if an extremely great current flows through the resislient plate. The thermostat has a bulging portion at an inner side of the housing to which the bimetal plate contacts, before the resilient plate contacts to an inner portion of the housing.
