Newbie hobbiest easy question

Hobbiest with model trains and home theatre. Lots to learn. E.G. I am hacking a computer speaker set's subwoofer to use on its own and need to install power switch. Have the plans ok, but Ques. I have on hand only very small SPST switch to use for power rated at 2 amps 250 V. Is this too small for the job?

Check YouTube video at Using a Triac to switch AC line. (The Triac in CircuitLab cannot be used in a simulation). They use an Arduino which emit a 0 volt or 5 volt, limited current to few milli-amp, to control the AC current. In your case, you could substitute the Arduino with you switch which, in reality, is also a sub-circuit which would emit either 0 volt, either 5 volt.

I should have added this reference too, very important for safety since that may involve "playing" with main voltage which may hurt you badly:
