A powered surgical tool with a switch for regulating tool operation. A pair of opposed arms extend outwardly from opposed sides of the switch. The arms move between safety and run states. When the arms are in the safety state, the arms engage a static surface to prevent movement of the switch. When in the arms are in the run state the arms are spaced from the static surface so movement is allowed. The arms are connected together so that the movement of one arm results in simultaneous movement of the other arm.
