[QUOTE="Chris BT Davis, post: 2845, member: 412"] I'm planning to tackle building a footswitch for a Rane RPM44. The aim is to use the 5VDC logic and latching switches to mute/unmute different processing paths, like a guitar amp footswitch. The switch and software is all easy. But, I'd also like to have a status led with each switch: Circuit complete = LED on. This seems as simple as adding the LED & resistor on the back side of the switch and letting the logic voltage power the LED's. I don't have quite the electronics know-how to feel comfortable that there isn't something I'm missing. Any advice? Am I on the right track with this? Is there any concern that powering 2-3 LED's would cause enough sag to cause the logic relays to see <5VDC (100ma power supply)? Apologies for the amatuerish question, but this is a little outside my normal scope. Thanks in advance for any help! [/QUOTE]
