Power-up starting power switch with controllable function

Abstract

The invention relates to a power-up starting power switch with a controllable function. The power-up starting power switch with the controllable function can effectively solve the problem of controllable power on and off of electric equipment. According to the technical scheme, the power-up starting power switch with the controllable function comprises a housing and a circuit board inside the housing, wherein the housing is provided with power input pins and a button S1; the circuit board is provided with a control circuit, which is composed of a single chip microcomputer, a field-effect tube and a DC / DC (direct current / direct current) module, the single chip microcomputer can control the input pins to output high electrical level or low electrical level according to input signals of the input pins. During application, an operator can simply connect the power input pins on the housing with the power supply output end of utilized equipment. The power-up starting power switch with the controllable function is novel and unique in structure, simple and reasonable in circuit, easy to produce and low in cost, achieves power-up automatic power ON, one-key power ON and OFF, low energy consumption, use convenience and high effects, and in a standby status, prolongs the service life of battery by 2 to 5 times, thereby being an innovation of power switches.

Description

technical field [0001] The invention relates to a power-on power switch with a controllable function, which is used in various circuits or devices that need to be powered on and automatically started, and is specifically applied in the field of electronic products with high safety, such as the field of automotive electronics. Background technique [0002] At present, in various devices that need to be powered on automatically, the usual method is to connect the power inlet of the device directly to the output end of the power supply, so that the device can be powered on and working immediately after the power is turned on, but this has disadvantages It cannot be turned off by pressing the button when the power is turned on. There is another method that can be used to turn on and off the button, but this method requires the device to continuously collect the status of the switch button, which requires the device to continue to detect the switch button even in the shutdown sta...

[0002] At present, in various devices that need to be powered on automatically, the usual method is to connect the power inlet of the device directly to the output end of the power supply, so that the device can be powered on and working immediately after the power is turned on, but this has disadvantages It is not possible to turn off the power by pressing the button when the power is turned on

There is another method that can be used to turn on and off the button, but this method requires the device to continuously collect the status of the switch button, which requires the device to continue to detect the switch button even in the shutdown state, which requires a certain amount of time. Power consumption is very unfavorable for battery-powered devices, and it is easy to cause battery power loss in the long run
