Mouth-operated switch device for microscope, has switch operated by mouth of microscope operator supported by longitudinally displaced carrier with fixing part and relatively pivoted part

摘要

The mouth-operated switch device (63) has a switch (69,71) operated by the mouth of the microscope operator, supported from a base by a holder having a rod and a mouth switch carrier (73) displaced longitudinally along the rod. The mouth switch carrier has a fixing part slid along the rod and a relatively pivoted part (95) for the mouth switch, coupled to the fixing part via a ratchet mechanism (97). An Independent claim for a microscopy device is also included.
