Abstract:
A switch assembly adapted for operative interconnection with a surgical light guide system having a remotely positioned light source for generating visible light, a light guide handpiece, and a light guide which guides visible light from the light source to the handpiece, said switch assembly being adapted for sleeved positioning around the handpiece of the surgical light system and comprising:a tubular electrically conductive inner base member adapted for sleeved positioning over the handpiece;an electrically conductive elastomeric outer member concentrically positioned in surrounding relationship to said base member;proximal and distal electrically non-conductive mounting rings for maintaining said elastomeric outer member in annular spaced relationship to said inner base member; anda shutter assembly operatively connected to said inner and outer members and adapted to being operatively associated with said light source to effect a change in visible light intensity in response to contact between said inner and outer members.
