Footnotes

  • Dr Matthaus Hipp (1813-1893) of Neuchatel patented his toggle switch in 1842.
    The Hipp toggle contact system involves a trailing toggle (a pivoted steel point) hung freely from the lower sprung contact. Fixed to the pendulum is a notched step which travels under the toggle, when the pendulum swing lessens the pointer engages on the with the notch and on the return swing the engaged toggle is forced upwards closing the contacts and thus giving impulse to the pendulum via the two electro-magnets.
    The introduction of the Hipp toggle was a very important advancement in electrical horology, and was used and adapted by many makers throughout the 19th and early 20th centuries. The proceeding lot, an electrical longcase by Bentley also employs a Hipp toggle.
