wireless remote control electric fan speed governor
The speed regulating of desk-top electric fan usually adopts musical instrument keys mutual-lock switch controlling inductor spindle head on or off to realize. If we adopt remote control circuit, controlling relay and changing inductance spindle head access or alteration can obtain the same function as the musical instrument keys, and control speed regulating remotely. The remote control transmitting circuit of this electric fan speed governor adopts finished product component TWH9236, which is not shown in the figure. Remote control receiving circuit uses TWH 9238, and data output end A is idle.
