Switch button for an endoscope

An endoscope comprising:

• a handle housing having a housing wall, the housing wall defining an interior compartment, the handle housing having an exterior surface and an interior surface, a plunger aperture, and two or more apertures extending from the exterior surface to the interior surface adjacent to the plunger aperture;
• an electrical switch positioned in the interior compartment and having an actuation surface and a carrier board opposite the actuation surface, the carrier board having two or more apertures corresponding to the two or more apertures in the handle housing, the plunger aperture overlapping, at least in part, the actuation surface;
• and
• an operating part comprising:
• a finger pad having a finger surface;
• a ring connected to and extending from the finger pad, the ring having a plunger aperture and an interior ring surface opposite the finger pad, the interior ring surface contacting, at least in part, the exterior surface of the handle housing;
• two or more legs connected to and extending from the ring, the two or more legs each comprising a spacer section having a peripheral surface and an electrical switch retention protrusion extending radially outwardly from the peripheral surface,
• wherein the two or more legs traverse the two or more apertures of the handle housing and the two or more apertures of the carrier board to align the plunger aperture of the handle housing with the actuation surface of the electrical switch,
• wherein the electrical switch retention protrusions extend through the two or more apertures of the carrier board and secure the electrical switch to the handle housing in a predetermined position, and
• wherein the finger pad comprises an elastically deformable material configured to extend, from a rest position, toward the electrical switch when pressure is applied to the finger surface, extension of the finger pad causing actuation of the electrical switch, and
• wherein the finger pad is biased to return to the rest position when the pressure is released.
