In my friend's entertainment system (TV, DVD player, etc) is plugged into a switched outlet (via circuit breaker) in his living room. The outlet is controlled by a simple light switch. Unfortunately, there are no other outlets against that particular wall.

When he has guests over (frequently), some will inadvertently hit the switch, turning everything off and resulting in him having to reset some devices. Needless to say, it's a pain. So he's resorted to taping the switch in the "on" position with masking tape.

I'd like to remove that switch for him. Can I just remove the switch and reconnect the wires with a wire nut, let the bare ground wire dangle in the junction box, and then cover the junction box with a cover plate (the kind w/o openings)? I know that this will work, but just want to make sure it's a proper way of doing it.

Thank you very much in advance.
