DZ-1000's do not need the DZ-1008 to wire with momentary toggle and led's. http://www.z-stuff.net/app17.html This is the instruction page. You will need to install a diode to direct which way the signal runs. Use aux power of 14V. They will not work on 10VAC. Do not use track power to activate the switches.
Could not find momentary toggle switch w/led's for the DZ-2500. You may want to contact Dennis, he may be able to help.
