I'm looking for circuit ideas that will allow multiple momentary NO switches to control multiple loads, but where only one load is to be energized at a time.
Here's the configuration and the desired behavior:
Master Switch
<Switch_1> < Switch _2> < Switch _3> < Switch _N>
<Load_1> <Load_2> <Load_3> <Load_N>
Master switch is a mechanical toggle switch.
All load controlling switches are lighted momentary NO.
On start up all loads are un-energized.
Only one load is to be energized at a time.
Pushing a switch will energize its load. Pushing the switch again will de-energize the load.
Pushing a switch for an un-energized load will de-energize any existing load and energize the load under its control. The switching should be break before make so as to conform to the desire for one load to be energized at a time.
Preference is for low voltage switches controlling line voltage loads.
Load currents are 5A max.
Desire that solution is flexible enough that any number of switch/load pairs can be daisy chained together.
Desire that solution is not micro-controller based.
I have found numerous circuits for latching momentary NO switches and they are easy to extend to multiple remote off/on switches for a single load, but I have not been able to find a circuit that meets my need and regrettably I'm not clever enough to figure out one on my own.
Thanks for any and all suggestions.
