Since the load receiver 12 is placed on the pressure switch 15 via the contact pin 14 so that the load of 2 is applied to the pressure switch 15 in a minute area, even a low load of snow can be collected by the load receiver 12. Therefore, pressure can be applied concentratedly to the pressure switch 15 in a small area,
Even if the pressure switch 15 with high load response is used, snowfall can be detected with high accuracy without malfunction. Moreover, this pressure switch 15 is made long, and the load receiving tray 1
By increasing 2 accordingly, the detection length can be freely changed and multi-point measurement in the measurement area becomes possible. Once the response load (Kg/cm 2 ) of the pressure switch 15 is determined, the snow load (g → cm) that responds also to the area of the load tray 12, the weight of the tray 12, and the contact area of the contact pin 14 can be determined. This can be determined and adjusted freely.

になる。 Further, the pressure switch 15 includes a pressure conductive rubber 22 that is configured to be energized by applying a predetermined load.
The physical properties of the contact pin 14 act as a sensor, and there is no need for the contact pin 14 to have an electrical function.
It is less likely to be damaged by rust or corrosion caused by snow, water, etc., such as a loss of electricity. Moreover, since the pressurized conductive rubber 22 is energized or de-energized depending on the presence or absence of a certain overload, it is possible to control the start and end of snow melting in the snow melting system using only this type of snow detection sensor, and the entire snow melting system can be controlled. Configuration becomes very easy.

る。 Furthermore, the snow detection sensor of the present invention can be installed anywhere, for example under a flexible snow melting system such as a rubber snow melting mat, which is very convenient and can be installed under the system in this way. Unlike the case where a sensor is installed on the system, there is no problem such as only the sensor part being difficult to melt into snow and causing inconvenience in the control operation of the snow melting system, and the practical effect is significant.
