I am looking to build a fairly basic circuit where a water level detector (shown in my diagram attached as a float switch) activates a 555 circuit which has an low output for a time, before going high and activating a solenoid, or in other words, a solenoid controlled by a float switch and activated after a delay. I would like it so that the float switch needs to be active for a given amount of time before the solenoid becomes activated and should the float switch be deactivated at any point the solenoid will remain or revert to a closed state. I have attatched a diagram that is somewhat functional in having a delay before activating the solenoid when the float switch is active, but the capacitor explodes if the float switch is deactivated. Any advice with this topic would be fantastic.
