I'm new to the forum, and a Biologist by profession. So please forgive me if my question seems rather simple minded and my use of terminology - peculiar.
I have a project I'm working on that makes use of a remotely operated wireless relay system ( look here ). The sender requirement for activating the relay is very simple, requiring only a contact closure input. Where I need help is in my design of the switch panel to operate the relay. Below is a description in its simplest terms...
I would like to ideally have a tact switch that when depressed (the first time) will activate a set of parallel continuous circuits. One circuit will be the contact closure input required by my relay sender. The second continuous circuit will activate a "reporter" LED - when the #1 contact closure circuit is closed (relay active), the LED will shine green. When the tact switch is pressed a second time, the contact closure circuit will be opened and the LED will shine red.
What I "think" I know:
A. There are two types of dual color LED, three terminal and reverse polarity, and I imagine either one could be derivatized to work in my application.
B. Linear Technology makes this push button on/off controller. I imagine this might be part of what I need.
What I'd like in the final device: I ultimately want something that is portable and battery operated, so I need low amperage components, i.e. miniature LEDs. I also want the sender to be as slim as possible, which is why I'm focused on tact switches. I know the transmitter will draw the most current, but I have no control over that.
I know I could design the switch panel using more traditional DPDT switches, but I'm hoping that you folks can tell me whether my "ideal" switch panel - as outlined above - is feasible. I'm willing to invest the time to build the prototype if it is, and would be very grateful if you can point me in the right direction as to what I might need to complete this project. If it cannot be easily done with tact switches, I'm open to other ideas - particularly if they incorporate "slimline" switches.
