How is the power cut controlled when the heater is dumped? The principle is simple.

Dumping power-off protection is one of the functions of various types of heaters. It can prevent the heater from working in a non-normal state of tilting or falling, resulting in a short circuit, and can prevent fires caused by short circuits.

The same principle is also applied in electric appliances such as electric fans, atomizers, vertical air conditioners, sports equipment, etc. In our daily life, when the fan falls down, it stops working, and when the fan is lifted, it works normally. So how do you implement the dumping power protection function?

The dump switch is an important component to realize the dumping and power-off protection function. Usually, the tilt switch with the angle set is mounted on the circuit board. For example, the setting angle is 30°, the recovery angle is 65°, and the tilt angle of the appliance exceeds 30 °, the dump switch gives a signal, the machine immediately powers off after receiving the signal to stop working, at this time the dump switch continues to work. When the tilt angle of the device returns to 65° or less than 65°, the dump switch gives a signal and the device starts to work. This is the principle.


The dump switch is divided into mechanical and electronic, the photoelectric dump switch is also a kind of dump switch commonly used in the market. Compared with the mechanical and electronic dump switch, the photoelectric dump switch has higher reliability and higher precision. The photoelectric tilt switch can realize 360° detection, and the tilting switch can detect the tilt change when the device left,right, forward and backward. The photoelectric dumping switch is small in size, long in life, and strong in seismic resistance.
