I have a 4 switch circuit that has 8 pin outs:
STB, SW1, SW2, SW3, SW4, GND, GND, +5V.
STB has 4.6v constantly
SW1-SW-4 are 0.15v when off, and 0.65v when down.
I am looking for a way to make it so that when SW1, SW2, SW3, SW4 are all equal to 0.65v each (so 0.65v * 4, or 2.6v), then I want to trigger sending 50v to a coil for 1 second, and then cut off the 50v.
So, I am wondering what my options for this are? Do I want to use transistors to construct AND gates, to detect when all 4 switches are ON? Or is there an easier way to do this? I also am unsure what my options are for limiting the 50v for a one-time 1 second time interval.
I'd love to hear whatever creative ideas you guys might have on this...
Thanks!
