These 16 switches allow save some screens in a quick way while I’m working so that I can call them rapidly when I desire it. When the switch is free it’s of a grey colour; when it’s engaged it’s of a green colour and when it’s chosen it’s of o red colour.

The last switch in the bottom on the RIGHT is use to blank the red chosen switch.

We have always to save the file of setting if we want to save the changes done to the switches.
