using a contactor with lights

    Thinking bout using this to control 2 lighting circuits on one switch, save on cable, just run 3 core 1.5mm out to switch and then go straight from the board to the lights (2.5mm) using the contactor.

    If there on for an average of 3 hours a day, would there be a problem with the contactor after a while with it being held on for 3 hours or am I worrying about nothin? What price are these in wholesalers?

    Also any idea where I can get a coin operated meter for the lights, not having any luck with google.

    contactors are commonly used for emergency lighting(n/c)

    and general lighting

    run a 4-core to your switch

    Why is it necessary for a 4 core?


  • Closed Accounts Posts: 4,431 ✭✭✭M cebee


    the 4-core will give you the 2 phase colours
    unless you're using singles

    But if I;m only using the switch to activate the contactor I will only need 3 core, I can sleeve the neutral or the earth and use it as the switch wire

    the diy guys can do that

    us registered guys have to spend the extra on the right colours:D

    a 4-core flex or 5-core nym will do for coin-meter control

    u could use a brown/brown twin and earth cable then ud have the proper phase colours contactor will also need a neutral,you shud have no prob using this contactor for any length of time there very commonly used for lights not sure on price though,if u only need to control 2 circuits a 2 pole contactor will be cheaper (4 pole contacter in above pic)

    just keep in mind any risk from 'blackouts' when designing a lighting system with coin-meters
