Figure 4 It is an internal diagram of a non-trigger state of a super-thin fall switch of the utility model, and the front shell 10 and the rear shell 11 are combined to form a cavity one 101 accommodating the counterweight ball 2, a cavity two 102 accommodating the lever flap 3, and a cavity three 103 accommodating the micro -switch 4; the cavity one 101, the cavity two 102 and the cavity three 103 are arranged from top to bottom and are mutually penetrated, so that the installation of the counterweight ball 2, the lever flap 3 and the micro -switch 4 is facilitated.

[0027] Refer to Figure 1 , Figure 1 It is a front view structural schematic diagram of a super-thin fall switch of the utility model, in order to prolong the service life of the fall switch and improve the heat dissipation effect, the lower part of the rear shell 11 is designed to be hollow, which can reduce the material cost and improve the heat dissipation effect; of course, the lower part of the front shell 10 can also be designed to be hollow, which can be opened according to actual needs; since the model and other parameters of the fall switch need to be written in the fall switch, one side must be fully covered.

[0028] Refer to Figure 5 , Figure 5It is a side surface structure schematic diagram of the ultra-thin fall switch of the utility model; the micro switch 4 and the shell assembly 1 are assembled, and there is an isolation space 5 between the micro switch 4 and the shell assembly 1 for facilitating heat dissipation of the micro switch 4; the isolation space 5 comprises an isolation space one 51 and an isolation space two 52; the isolation space one 51 is located between the front shell 10 and the outer side of the micro switch 4; the isolation space two 52 is located between the rear shell 11 and the outer side of the micro switch 4; the heat dissipation mode of the two sides can make the micro switch 4 have a longer service life.

[0029] Referring to Figure 1 , Figure 3 and Figure 4 , Figure 1 It is a front view structure schematic diagram of the ultra-thin fall switch of the utility model; Figure 3 It is an internal diagram of a triggered state of the ultra-thin fall switch of the utility model; Figure 4 It is an internal diagram of a non-triggered state of the ultra-thin fall switch of the utility model; the counterweight ball 2 is a circular steel ball; in order to adapt to the circular steel ball, the cavity one 101 is designed into a spherical shape, facilitating the counterweight ball 2; moreover, the overall size of the cavity one 101 is greater than that of the counterweight ball 2, and the upper opening of the cavity two 102 is smaller than the size of the cavity one 101; when the fall switch falls, the counterweight ball 2 falls into the cavity two 102 due to gravity, thereby pressing the lever tab on the cavity two 102, so that the power supply of the electrical equipment can be disconnected, and the electrical equipment can be stopped.

[0030] Working principle: when the equipment installed with the fall switch tilts or falls, the counterweight ball moves under the action of gravity and triggers the lever tab. The deformed lever tab pushes the micro switch, making the switch contact close or open, thereby sending an alarm or starting an emergency response mechanism. At the same time, the design of the isolation space ensures the heat dissipation performance of the micro switch, prolonging the service life.
