[0027] Please refer to Figures 1-6 The utility model provides a sensor that draws power from a switch, comprising an outer shell 1, a circuit board 2 disposed inside the outer shell 1, and a sensor detection element mounted on the circuit board 2;

[0028] The outer shell 1 includes a sealing cover 11 and a fixing frame 12 sealed with the sealing cover 11; the fixing frame 12 is installed on the outside of the switch;

[0029] The fixing frame 12 includes a sealing bottom plate 121 sealed to the sealing cover 11 and two L-shaped fixing rods 122 arranged opposite to each other at the ends of the sealing bottom plate 121. The L-shaped fixing rods 122 are installed on the rear side of the switch panel in close contact with the wall.

[0030] In this embodiment, the outer shell 1 is used to seal and protect the internal circuit board 2 and sensor detection element and fix it to the outside of the switch to facilitate power supply from the switch; after the circuit board 2 and the sensor detection element are placed on the fixing frame 12, the sealing cover 11 is fastened to seal the circuit board 2 and the sensor detection element therein, and then the L-shaped fixing rods 122 are installed on the rear side of the switch panel in contact with the wall, so that the two L-shaped fixing rods 122 are stuck to the outside of the switch outer shell, thereby enhancing the stability of the installation; the fixing frame 12 is formed as an integral part, which enhances the stability of the overall structure.

[0031] This device connects the wires of the circuit board 2 in parallel with the wires of the switch, and uses the current of the switch to power the circuit board 2 and the sensor detection element. This method makes it more convenient to obtain power and can make the entire device lighter. The circuit board 2 is fixedly installed near the switch through the outer shell 1, which facilitates the observation of the sensor reading.

[0032] like Figure 5-Figure 6 As shown, the tail end of one L-shaped fixing rod 122 has a first hook 1221 and a first groove 1222 with an upward opening, and the tail end of the other L-shaped fixing rod 122 has a second hook 1223 and a second groove 1224 with a downward opening; the first hook 1221 is gap-engaged in the second groove 1224; the second hook 1223 is gap-engaged in the first groove 1222.

[0033] In the embodiment, the tail of the two L-shaped fixing rods 122 can be clamped on the outside of the switch control panel flexibly, and the clamping degree can be adjusted in a small range, thereby enhancing the flexibility of the device.
