    Hello,

    I'm working on a project trying to switch two sets of lights on and off alternating. The voltage is 120 vac and about 7 amps. They will switch on and off two times every second. My question is, is there anything else I can use to switch these two circuits becides a relay that can handle this large of a load? I'm new to circuits. Thanks for any help.

    Yes, there is something other than a relay that can do what you would like and be more reliable. Relays generally are not designed to switch loads on and off in a rapid sequence so you will end up replacing them often. Key words to google are: SCR, Triac, Thyristor. All of those are are roughly the same thing, sort of. They are discrete semiconductor devices designed to switch AC loads.

    Thanks for the info! It will be getting switched on and off by a 555 timer circuit.
