  • Patent number: 6627828
    Abstract: A gas flow control and igniter switch assembly for a gas appliance includes a valve body having a stem, an igniter activating switch and a knob, wherein the igniter is activated upon depressing of the knob a predetermined distance. The igniter switch is preferably constituted by a multi-piece outer casing within which is mounted multiple igniter contacts, an electrical connector, and an activating member. The activating member carries the electrical connector and is biased to a position which maintains an electric circuit to the igniter open. The multi-piece outer casing is adapted to be snap-fittingly secured together and mounted about the stem of the valve. Preferably, the stem extends freely through the outer casing but press-fittingly receives the activating member such that the activating member moves in axial unison with the stem.

  • Patent number: 6608267
    Abstract: A foot switch for use in the control of medical apparatus comprises a pedal that is connected to and movably seated on a floor plate of a joint connection, a sensor linked to a switch element, and a repositioning device disposed between the floor plate and the pedal. The repositioning device ensures that an operating force must be applied to the upper surface of the pedal to produce a tilting movement of the pedal out of an initial position into an operating position in which a smaller angle is defined between the floor plate and the pedal than in the initial position and in which the sensor is activated to trigger the output of a switch pulse from the switch element. The improvement of the present invention consists of the combination of the repositioning device and the joint into an elastic joint device. The simplified foot switch is easily disinfected.
