The wireless multi-coding multichannel synchronizing signal circuit switch has the characteristics that: a signal output pin of the 2272 chip is electrically connected with the resistor; the other end of the resistor is respectively and electrically connected with B poles of a plurality of 1 AM triodes; E poles of the plurality of 1 AM triodes are electrically connected; and C poles of the plurality of 1 AM triodes can be respectively and electrically connected with poles in the controlled signal circuit switch.

Description

Technical field [0001] The wireless multi-code multi-channel synchronous signal circuit switch relates to a device in which a 2272 chip (2272 remote control decoding circuit) obtains a wireless coded signal through a receiving head, and after decoding, controls the controlled signal circuit switch of the controlled device to achieve the purpose. Background technique [0002] Currently known wireless multi-encoding circuit switches based on 2272 chips are made up of various function decoding chips such as 2272M and 2272L of various brands, receiving head supporting and oscillating resistors, multiple, multiple capacitors, resistors, triodes, and relays. The 2272 chip obtains the wireless coded signal emitted by the peripheral equipment such as the wireless door magnetic detector through the receiving head, and after decoding, it triggers the on-off of the relay through a variety of capacitors, resistors, and triodes to form a switch. However, due to the use of relays or even m...
