We are making some great headway in being able to have the latching DPDT lighted rocker switches of the upper console able to generate a short momentary pulse for the random DTMF tone request of the Voice box using the LM555 timer chip and a few other components.
Here is a diagram showing how I have the switches wired up to the 555 timer circuit. this is really great because originally I thought I was going to need a separate circuit for each on on the rockers. by this method I can get away with once circuit for the upper console's latching switches and one circuit for the lower console's latching push buttons. I should mention that I change the value of R1 to a 200 K resistor and this allows me to flip the switches fairly quickly and still get the needed pulse for the DTMF request. Also for 10 switches R2 is being swapped for a 470 K Resistor. Not that 10 switches can be on at any given time as there are 5 DPDT rockers so only 5 devices can be on at any given time with this circuit so it should be fine I am told.
