Embodiment Construction

[0011] Please refer to figure 1 , the first preferred embodiment of the circuit for preventing electrified operation of the main board of the present invention includes elastic switches S1, S2, electronic switches Q1-Q4, resistors R1-R9, capacitor C, alarm W, output terminals O1-O3 and power supply VCC1 -VCC4.

[0012] In this embodiment, the power supply VCC1 is a battery that can provide a voltage of 3V. The power supply VCC2~4 is the 12V, 5V and 3.3V backup power provided by the power supply to the motherboard after the electronic equipment (such as a computer) is connected to the AC power.

[0013] Alarm W is a buzzer.

[0014] The elastic switches S1 and S2 are mounted on a case of an electronic device (such as a computer), and a case cover is detachably mounted on the case.

[0015] The elastic switches S1 and S2 respectively include pin 1 , pin 2 and pin 3 . The elastic switches S1 and S2 are normally open switches, and when they are not pressed, the pins 1 and 2 ar...

Abstract

The invention provides an electronic device and a circuit for preventing a main board from being operated with electricity. The circuit includes a flexible switch, a first power source, a plurality of first electronic switches and a plurality of second power sources with different voltages. The flexible switch includes a first pin and a second pin, the second pin is grounded, and the first pin Connect the first power source, the first end of the first electronic switch is connected to the first pin of the elastic switch, the second end of the first electronic switch is respectively connected to these second power sources, the box cover is buckled and the elastic switch is pressed, and the The second pin is connected to the first pin, the first electronic switches are turned on, the third ends of the first electronic switches provide power to the motherboard, and the box cover is removed to restore the elastic switch to its original state. The second pin is disconnected from the first pin, the first electronic switches are turned off, and the third terminals of the first electronic switches have no power supplied to the motherboard. The circuit of the present invention for preventing the main board from being operated with electricity can avoid operating the main board with electricity.
