    Hi, I need a circuit to switch off a current for around 60 seconds when triggered.
    I have purchased a 555 monostable switch, is this something that could work for this purpose?

    Yes you could use a 555 in "one shot" mode to drive something else like a relay or transistor to control the load.

    More detail if you expect help

    ok thank you

    what i have bought is this
    http://www.maplin.co.uk/555-monostable-switch-kit-220009

    i have a cable with a low current at 12v constant.

    what i need is a cheap compact solution to switch this off for 60 (ish) seconds
    a variable timer option would be good.
    i dont have equipment for pcb production unfortunately

    is this maplins product above capable of one shot mode?

    thanks for the help
