Abstract:

An illuminated knob for indicating the operative condition of an appliance having a light operatively coupled to the knob, an attitude sensing electrical switch, and a compartment for a replaceable voltage source. Operating independently of the appliance energy source, the light illuminates when the knob is rotated to a position corresponding to an âonâ condition of the appliance, signaling the operative status of the appliance to the user. The light goes off when the knob is turned to the âoffâ position, indicating the safe and inoperative condition of the appliance. The knob requires no activation other than installation of the front surface mounted battery and all parts are sealed within the knob housing for reliability and safety.
