In DC voltage applications, the RC snubber network is typically wired across the relay contacts, whereas in standard AC ...

After construction, power up the circuit from the concerned RC channel (e.g. channel 5) of the receiver, turn on your transmitter, and verify that moving the R/C stick (or an auxillary toggle switch ) ...

An RC circuit in series with the coil allows full-current turn-on for reliable relay operation, then reduces the current to save power. Fellow engineer Sanjay R. Chendvankar of Mumbai, India ...
