    Just for fun I designed and built this simple circuit which drives a monostable relay by a singol momentary button.
    Supplied by 24VDC the circuit works for a 12V-140 ohm coil. The relay should feature a time response of 5 milliseconds or less.

    Components
    R1 -470ohm
    R2 - 22Kohm
    R3 - 180ohm - 3W
    R4 - 150ohm -3W
    C - 470uF
    K - relay coil - 12VDC -140ohm - 3 milliseconds
