Abstract
A surgical handpiece ( ) for performing medical procedures. The handpiece ( ) has a housing ( ) and a membrane switch assembly ( ) is mounted to the housing for regulating the operation of the handpiece. The membrane switch assembly has a switch plate ( ) mounted in a cavity ( ) formed in the housing. The switch plate includes a pair of spaced apart contact pads ( ). A dome ( ) formed of flexible metal is spaced over the contact pads. A keypad ( ) extends over the top of the switch cavity to cover the switch plate. A bezel plate ( ) is fitted over the keypad. The keypad is compressed between the bezel plate and the housing to form a seal around the switch cavity. Depression of the keypad results in the dome flexing inwardly and closing the connection between the contact pads.
