    Good evening everyone,

    I wanted to submit a question that is certainly easy to resolve for you, I have 8 toggle switches (on/off) which have the following characteristics:
    direct current 12Volt 20 Ampere.
    What kind of low-cost circuit would you suggest to drive 8 Alternating Current lamps independently?

    It would be excellent a scheme to guide me to the construction with the relative components to buy.

    Thanks to all the people who wanted to support me, apologizing in advance for the triviality of the question, but having a problem with dyslexia everything becomes complicated.

    If you do not clarify what type of lamps you have, it is difficult to give you answers.
    A mechanical DC switch can also be used without problems in AC.
    From the description 20A to 12V are nice big switches can handle important loads.

    I thank Amilcare for the clarification, here is the material I have ( for convenience I got it from the internet)

    I was told that switches connected directly to it burn out 220, for this reason I turned to you.

    Thanks again

    They are right they are only for 12V
    An adapter is needed to drive 230Vac lamps (relay).
    Here you can find something that can go https://www.ebay.it/itm/10-pz-Relay-12Vdc-3A-da-circuito-stampato-rele-12V-1-scambio-ART-DY07-/331276366520?mkcid=16&mkevt=1&_trksid=p2349624.m46890.l6249&mkrid=724-127637-2357-0

    Thank you!

    So I can connect the relays you proposed directly to the bulb wires and they do not burn out? I should put some resistances in the case?

    Tomorrow I'll post you a complete outline

    The celestial rectangle is the relay seen from below, none of the components are to scale but so the drawing is easily understood but, if you have any doubts, just ask
    NB the scheme is on the next page
