Bistable, astable, monostable, and astable. TOP SWITCH : OFF(RED)
BOT SWITCH: ON(GREEN)
Same as my 3 555 in series without potentiometers, and with added bistable 555. On(green) is the high state and activates the circuit, off(red) is the low signal to shut off circuit. Wired so the as table timing pulse stays on.
Sometimes can't find solution if you shut off during a pulse cycle, need to fix
