Simple switch that "Remembers" state at power up? I've been trying to design a switch that, when a relay (spdt) is energized: -if a reed switch is closed, a 12v green light bulb drawing 2.5A stays lit until the relay is de-energized, regardless if the contacts of the reed switch open/close again. -if the reed switch is open, a 12v red light bulb drawing 2.5A stays lit until the relay is de-energized, regardless of if the reed switch contacts open or close again. Ive built several things with relays and logic gates and it seems i can build a simple latch for either, but if the reed switch is open when the relay is energized, and it then closes while the relay is energized, the light goes from red to green. I have at my disposal all the resistors you would expect, 1n4148 and 1n4007 diodes, TIP31A, 3904 and 3906 transistors, as well as 555 times, 4017 ICs, as well as quad NAND gates and lots of relays if these can be used-if not i can always get other components. Thanks alot in advance-there must be an easy way to do this.
