I have a circuit with a single momentary on switch that causes a solenoid to change position. I need to be able to see which position the solenoid is in. I've looked at the circuits for motor control LEDs on and off and I don't think that that will work for me.
I need the LEDs to indicate both states of the solenoid. One LED (green) = ON when the solenoid is on (red is off), and the other LED (red) = ON to indicate when the solenoid is off (green is off). I can't get this with a single LED because the off state would not be indicated.
I can't change the switch to a double throw switch I have to use the single pole single throw momentary switch. I can get back 12V indicating the solenoid is on or off from the live terminal. I can't use a relay in the space I have, I would like a diode biased solution if possible. I have 12 volts at the Led position which is remote from the solenoid.
