Anti-interference intelligent switch

The utility model provides an anti-interference intelligent switch which is composed of an input module, a microcontroller and a relay, the input module is electrically connected with the microcontroller, and the relay is electrically connected with the microcontroller. The input module is started by pressing or touching to generate a control signal and transmit the control signal to the microcontroller, the control signal is processed and calculated to generate an anti-interference signal, the anti-interference signal is restored to the control signal, and a signal output level is generated and transmitted to the relay. The relay controls the operation of at least one subsequent electric appliance according to the high and low signal output level, and the interference of an external signal shielding device can be avoided in the process, so that the subsequent electric appliance can be controlled to perform correct operation through the relay by performing one-key switching from the input module. 本实用新型提出一种防干扰
