Problems solved by technology

However, the existing power-off switches need to be operated by people, and cannot automatically cut off the power supply at the first time when a fault occurs. When the electrical appliance or circuit is just short-circuited, the spark is small, the smell is small, and the impact is small. It is difficult for the driver to find out in time. It is too late to operate the electromagnetic power-off switch or mechanical power-off switch to disconnect the power after the short-circuit hot spot

Abstract

The invention discloses an automatic power-off switch having a temperature sensing function. The automatic power-off switch having the temperature sensing function includes a housing; a wiring portionand a temperature sensor are arranged outside the housing; a controller, an elastic member, a movable plate and conductive plates are arranged in the housing; the controller is connected to the temperature sensor; one end of the elastic member is connected to the controller, and the other end of the elastic member is connected to an upper surface of the movable plate; and the conductive plates are movably conductive with the wiring portion outside the housing through the movable plate. The automatic power-off switch is simple in structure, and can automatically power off according to temperature change.

Description

technical field [0001] The invention relates to the technical field of electrical components, in particular to an automatic power-off switch with a temperature sensing function. Background technique [0002] The power-off switch is divided into electromagnetic type and mechanical type. The electromagnetic type is used to control the switch to connect the electromagnetic coil circuit, and uses electromagnetic suction to connect the moving contact with the static contact, thereby connecting the load to the power supply; the mechanical type is used to pull the switch manually. The switch handle connects the moving contact with the static contact, and turns on the vehicle power supply. Whether it is an electromagnetic or mechanical power switch, its purpose is to cut off the power supply when the circuit fails (short circuit, fire, etc.), so as to avoid burning, personal injury and other vicious events. However, the existing power-off switches need to be operated by people, and...
