The ES02 is a comfortable external switch set developed by SilverStone for wirelessly turning a computer on and off, as well as restarting it. Utilizing existing standard 2.4 GHz RF wireless technology, an internal 9-pin USB 2.0 connection, and the power/reset pin headers on a motherboard, the ES02 set can be easily installed and used within 20 meters of a connected computer. Thanks to the included Y-cable, the case's own power and reset buttons can also be used alongside the ES02 if needed. For those seeking a simpler security solution than software access control, the ES02 is a great alternative. It is also an excellent choice for computers located in hard-to-reach places or requiring special usage scenarios.
