Hello, I am designing a State-Of-The-Art voice evacuation panel, and I am now working on the voice command module, and there are a variety of buttons, to give some examples: EVAC, ALERT, PHONE PAGE, ALL CALL, STROBE, ALL CALL MINUS, etc. What I want to know is if I should use a latching relay for my design, which implements membrane buttons, I'd prefer a device in a DIP packaging, but if I have to resort to relays, I will, and it must meet RoHS standards and be lead free, as the entire panel will be.
