Novice here,
I want to build a circuit that will employ 2 relays, one to close and release the speakerphone button on my telephone, then 1/2 second later the second relay would close then release the redial button. The phone requires the release of the speaker phone button b4 it allows redial. Could the attached circuit work by connecting the speakerphone relay to the output of timer A, then the redial relay to the output of timer B.


Thanks,
Haxxx.
