@ogden - no need to draw the schematic. I understand what you're saying. Thank you for your help! :D |

Any progress? |

Hey Ogden! Yes, I've ordered the parts I need. Won't be able to start modifying and testing the unit until after Christmas. The switches read at 200mA 12VDC with a multimeter (no markings on them), so I ordered bat42 .2a/30v diodes. Thing is - the push button switch I have available for this project is rated 5A 125/250VAC. Another user on the board said I shouldn't have issues with this, so I'm going to test it when I get a chance before ordering more parts. The centre pole of the existing switches are connected to the microphone, so believe it is the positive rail. |

Overrated switch cannot be an issue. Thou I am not sure about your "switches read at 200mA 12VDC" measurement, but whatever. It is not that important anyway. Connect one or two existing switches to new switch and test. If does not work - you shall reverse diodes and test again. That's it - as easy as that. |

I appreciate your help my friend. I'll post when I've got everything in place! RE the multimeter test - I tested to see what the current was flowing through those switches when they are and are not actuated. Curious what result you might've been expecting? (learning the lingo here...) |
