CA 2525773
A circuit breaker for warming lamps mounted in a livestock barn is disclosed. The circuit breaker includes a housing divided into symmetrical housing parts, through which a power supply cable and a power output cable pass, and which are combined into a single body through ultrasonic fusion welding. A power switch is exposed outside the housing, while a micro switch is mounted in the housing. An ON/OFF actuator to actuate the micro switch is mounted in the housing. A warming lamp is connected to the ON/OFF actuator and is also connected to the power supply through both the power switch and the micro switch. A spring is provided in the housing such that, when the ON/OFF actuator is biased downwards by the weight of the warming lamp, the spring is compressed, and, when the weight of the warming lamp is removed from the spring, the spring extends to bias the ON/OFF actuator upwards. The circuit breaker, having a simple structure, increases work efficiency in the assembly of its parts, maximizes productivity, reduces production costs, and reduces its weight and volume. The housing has a hermetically sealed structure to prevent water from infiltrating into the housing, thereby solving the problems caused by conduction of electricity from the circuit breaker.
