The universal serial bus (USB) port has a built switch actuator that automatically turns power on and off upon insertion and removal of a USB plug. The switch for universal serial bus comprises of a USB port with a switch actuator in a power-off position and a momentary switch wherein when a USB plug is inserted into the USB port, the switch actuator is depressed which in turn depresses the momentary switch to turn on the power to the USB port. When the USB plug is removed from the USB port, the switch actuator returns to its original power-off position thereby turning off the power to the USB port.
