Abstract
A hand switch for removable attachment to a powered surgical tool. The switch includes a ring formed with a slot that is snap fit over the tool with which the switch is used. A manually actuatable lever is pivotally mounted to the ring. Internal to the lever is a magnet. The position of the magnet is monitored by a sensor internal to the tool. A tab extends inwardly from the ring. The tab seats in a notch integral with the tool. The seating of the tab in the notch aligned the switch with the sensor internal to the tool.
