Controlling two devices with the same push button
Depends on the devices but if they can tolerate a minor voltage change, you might try something like this. Components selection may need to change based on your specific equipment. I just put the volt meters in to illustrate the voltage on the load is somewhat lower than without the diodes. I don't recommend this method... But in a pinch...
