  • Patent number: 5926099
    Abstract: An electronic position signal device (10) that, when attached to a toilet lid (80), provides an audible and/or visual signal to indicate that toilet lid (80) is in an upright position. Position signal device (10) comprises a battery-powered electronic signaling module (20) with a transducer (30) for generating audible and/or visual signals similar to those used in greeting cards, and a position-sensitive switch (40). When position signal device (10) is used as a toilet lid position signal, position-sensitive switch (40) is a gravity-actuated switch which is closed (44) when the toilet lid position signal is in an upright or vertical position and open (42) when the toilet lid position signal is in a horizontal position. Closure of switch (40) activates signaling module (20) thereby causing transducer (30) to generate an audible and/or visual signal. Three gravity-actuated versions of switch (40) are described for bridging a gap between contacts (26A and 26B) which commonly are part of signaling module (20).
