[0021] The aforementioned electrical switches with anti-accidental touch function can be further optimized and / or improved according to actual needs:

[0022] Example 2: As an optimization of the above examples, as shown in the appendix. Figure 1 , 2 As shown, a front-to-back rotating shaft 8 is fixedly installed inside the movable hole 7. The rotating shaft 8 is located on the upper left of the button switch body 2. The pressure block 5 is rectangular and is rotatably installed on the outside of the rotating shaft 8 in the middle. There is a gap between the lower right side of the pressure block 5 and the upper end of the button switch body 2.

[0023] Depending on the requirements, the upper side of the pressure block 5 is an upward-opening arc surface for easy pressing, and the rotating shaft 8 can also be fixedly installed on the upper inner side of the movable housing 3. In use, in the natural state, when the pressure block 5 is pressed, the outer side of the pressure block 5 rotates and cannot touch the button switch body 2. This effectively prevents accidental touch that could cause changes in the switch state and improves the safety of the electrical switch.

[0025] According to requirements, the thread direction of the threaded hole of the left unlocking assembly 9 is opposite to the thread direction of the threaded hole of the right unlocking assembly. The thread direction of the screw rod of the left unlocking assembly 9 is opposite to the thread direction of the screw rod 10 of the right unlocking assembly. In use, two fingers press the two guide rods 13 so that the two racks 12 drive the two gears 11 to rotate. At the same time, the left end of the guide rod 13 acts on the reset assembly, the reset assembly stores energy, and the two gears 11 rotate to make the two screw rods 10 rotate and then move downward, thereby driving the movable shell 3 to move downward. In this way, the pressing block 5 moves downward with the movable shell 3, and then the right part of the pressing block 5 is pressed downward to swing downward, so that the right end of the pressing block 5 presses the button switch body 2, that is, the switch can be stably controlled. After the two guide rods 13 are released, the reset assembly resets to push the rack 12 to move and then reset. In the resetting process, the rack 12 drives the gear 11 to rotate in the opposite direction. The screw rod 10 rotates with the gear 11 to make the movable shell 3 move upward. The movable shell 3 drives the pressing block 5 to move upward and keep a certain distance from the upper end of the button switch body 2. In this way, the pressing block 5 cannot touch the button switch body 2, so that the change of the switch state caused by accidental touch can be effectively prevented, and the safety of the electrical switch can be improved.
