An overheat and overload sensing device includes a thermal sensor (such as a thermal regulator) and a breaker connected in parallel and used to cut off a power supply in case of current overload. The thermal sensor usually disposed near a heat source can respond automatically to cut off a local circuit in time in the case of overheat that will make the breaker become overloaded to break off power supply.

Overheat and overload sensing device

An overload protective circuit breaker switch including: a first fixed contact and a second fixed contact adapted to connect an electric appliance to power supply; a movable contact adapted to form with the first fixed contact and the second fixed contact a normal open contact; an actuator controlled by the user to turn about an axis; a lever coupled to and turned with the actuator, the lever being turned about a first bearing point, when the overload protective circuit breaker switch is not at an overload status, to move the movable contact between a normal open contact position in which the movable contact form with the first fixed contact and the second fixed contact a normal open contact, and a normal close contact position in which the movable contact form with the first fixed contact and the second fixed contact a normal close contact; and a release mechanism adapted to move the lever, the release mechanism releasing the lever from the first bearing point to a second bearing point upon an overload, causing the lever to release the movable contact and to let the movable contact return to the normal open contact status.
