ABSTRACT:
A mouth held switch assembly which is adapted to be connected to an electrically actuated surgical implement. The switch assembly is designed to be operated only by a clamping movement of the front incisors of the user. The switch assembly includes an elongated, thin walled, L-shaped, tubular housing, one end of which fits into the mouth of the user. A pair of electrical contacts formed on spaced blades are sealed in the leg of the housing which is insertable in the user's mouth. The contacts are connected to electrical leads extending out of one end of the housing. A portion of the housing is weakened adjacent the contacts with the weakened portion being protected by guards which permit only the incisor teeth of the user to contact the weakened portion of the housing, when the housing is inserted in the user's mouth. When the user bits down on the weakened portion of housing, the contacts are closed, thereby actuating the surgical implement.
