Hi

I have just purchased a 5V 433MHz Single Channel Relay and want to know what the connectors are for , as in the attached photo .
I know the GND /VCC , and I guess the CK/COM/CB are NC or NO Contacts ! , but not sure what the HC is for .
Cheers

No manual? Link to the purchase site? My guess is it's for a local trigger switch.
 
There is no manual for it , there is some mention of HC I have just found for a simular product and it says HC: push button switch ! .

cheers
 
On another board it looks like a pushbutton switch is connected between Vcc and the trigger (your HB?).
 
Yes that sounds about right , think I will try it , prob a manual way to operate the relay if the remote stopped working !
 
Attached is the data sheet on the relay. That should help.
