I find useful to have one or more of this switchboard (depending on how many machines you have). In my studio I had many devices without a power button (or, at least, without a power button on the front panel, so sometimes it could be boring to switch them on/off singularly.
The switchboard is well built, with a fuse protection for each socket, and a red lighted button always useful to better understand which machines are powered.
On the rear button the socket are schuko type, but you can also use a bipolar types (without ground shield). However, it's preferable to use straigh schuko because:
- with bipolar you won't use the ground pin (and there's also a worst galvanic connection and they can go out from the socket very easy)
- with the schuko, it you use angled connectors, you should consider to increase the space between this rack unit and the next ones
