    I have done many very simple circuits with switch. but the switch i am always using is the switch mostly used on homes. isn't it OK?

    because this switch is rated as 3A/250V and the other one 16A/300V but no indication if VAC OR VDC.

    so guys, is it OK to use those switches??????????????????????

    Those switches are fine if a bit cumbersome.

    In general if it only calls out 300V it means AC..

    For hobby work it is fine but DC is harder the break than AC so I wouldn't go over a few amps and no more than 32VDC.

    You have said in an earlier thread that you wanted to use a 15 amp fuse. Your switch should then be rated for more than 15 Amperes, or it will protect the fuse by melting first.
