Foot control mechanism for a dental apparatus |
摘要 |
A foot control mechanism for a dental apparatus has a tiltable actuation member mounted on a base part and an arrangement for holding the tiltable actuation member in a neutral position, which requires sufficient force to move the actuation member in either direction from the neutral position to a switch position. To accomplish this, the structure includes a mounting arrangement utilizing a pair of spaced-apart bearings extending parallel to each other which bearings receive projections on the other element and, preferably, a catch member is provided which provides a resistant force from movement from the neutral position.
