Therefore, the temperature of the electronic switch 20 can be acquired by the temperature measuring device 51, the occupied area of the temperature measuring component 50 on the insulating heat conducting strip 30 can be reduced as much as possible, the influence of the temperature measuring device 51 on the heat conducting effect of the insulating heat conducting strip 30 can be reduced to the greatest extent, and the heat radiating effect of the heat radiator 40 on the electronic switch 20 is ensured. Of course, the design of the present application is not limited thereto, and in other embodiments of the present application, the temperature measuring device 51 may also be installed by providing a receiving groove on the insulating heat-conducting sheet 30.

It can be understood that, after the insulating heat-conducting strip 30 or the electronic switch 20 presses the temperature measuring device 51 to deform the circuit board 53, the elastic restoring force of the circuit board 53 can make the temperature measuring device 51 elastically abut against the insulating heat-conducting strip 30 or the electronic switch 20. Therefore, the abutting tightness of the temperature measuring device 51 and the insulating heat conducting strip 30 or the electronic switch 20 can be improved, the temperature measuring device 51 can be fully contacted with the insulating heat conducting strip 30 or the electronic switch 20, and the accuracy of temperature detection of the electronic switch 20 is further improved.
