With the help of the buttons we have the option of switching on one or the other machine individually and switching on or off both at the same time.
The perfect solution for people who use two different razors when tattooing. With this switch to work, you only need one power supply and you will not have to unplug it every now and plug in the cable to change the razor.
Plug on large JACK to connect to the power supply
Convenient switch for control between the machines
