    Hi,
    I would like to design relay timer circuit using 555 timer and 12V relay. I want my design to be in such criteria:

    Requirement:

    First I will set the timer (for exampe 10s). Then I turn on the power (the 12V). After 10s, the relay will switch from (NC) to (NO) and stay in such a condition. The relay will only switch back to NC when I turn off the power.

    Anyone got any idea how to design this circuit. Can it be achieved using 555 timer or need other IC? Please advice.
    Thanx.

    Nick
