There are adapters with 3 ports, such as 8730, 8630, 8030 etc.

In my special case I do not need a powerline connection - I only need a switch plugged into directly 220 socket:





Usually people use a simple switch in such cases.
But I need a switch which is plugged unto 220 socket directly without any power cables or power supply adapters.

So, the question is - will it work?
Can I use 3-port powerline adapter as just a simple 3-port switch?
