Abstract

The invention belongs to the technical field of switches and particularly relates to a control circuit and a switch device. The control circuit comprises a voltage generation module and a frequency generation module, wherein the voltage generation module is connected with an external power supply, external equipment and a frequency generation module and is used for receiving the voltage of the external power supply and a working signal of the external equipment, converting the voltage of the external power supply into at least two voltages according to the working signal and outputting one ofat least two voltages to the external equipment according to user input; the voltage generation module is further used for supplying a bias voltage to the frequency generation module; and the frequency generation module is suitable for being connected with the external power supply, generating a first frequency signal according to the bias voltage and the user input and outputting the first frequency signal as a working frequency to the external equipment according to the user input. According to the control circuit, different voltages and frequencies can be supplied according to different equipment, and the practicability is strong.

Description

technical field [0001] The invention belongs to the technical field of switches, and more specifically relates to a control circuit and a switch device. Background technique [0002] In signal transmission and voltage supply, the switch is used as a control device for turning on or off, and can also be used as a device for providing operating voltage and frequency. For example, in the signal detection process, the signal of the device to be detected needs to enter the signal detection device through the switch device. At this time, the switch device provides the operating voltage and frequency for the device to be detected. However, the switch device in the prior art is only for One type of equipment to be tested provides one voltage and frequency. When multiple types of equipment to be tested require signal detection, multiple switching devices need to be added to provide voltage and frequency, which is very low in practicability. Contents of the invention [0003] In vi...
