A SSR can be used to switch on and off an AC circuit...

 

[BradtheRad]

An IC named 4066 is able to switch AC signals. 'Quad Bilateral Switch'.

The signals need to be within its amplitude and current limits.

Back to back connected FETs.

Back to back connected SCRs.

 

[Tahmid]

You can use SCRs, triacs, optotriacs, solid state relays and even MOSFETs/IGBTs.

Contactor can also be used to on/off ac easily.
