ABSTRACT:
A switching apparatus is provided includes an output device, a power supply for providing power to the output device and a finger-mounted switch connected between the output device and the power supply. When the finger to which the switch is mounted is in a first position, current flows from the power supply to the output device. When the finger is moved into a second position, current flow is prevented. In one embodiment, the output device is an electrosurgical cautery mounted on the finger in the same housing as the switch. The cautery tip extends from the housing and is energized when the finger is in the first position and is positioned within the housing and is deenergized when the finger is in the second position.
