1. A liquid level switch comprising:

  • (a) a first elongated, non-electrically conductive substrate having a pair of elongated electrical conductors thereon;

    (b) a second elongated non-electrically conductive substrate having an electrically conductive area thereon, said electrically conductive area being positioned over the pair of electrical conductors positioned on the first elongated non-electrically conductive substrate for enabling electrical bridging contact between conductors of said pair of electrical conductors; and

    (c) a substrate coupler for coupling said first and second non-electrically conductive substrates together face to face for providing separation of said non-electrically conductive substrates in the absence of hydrostatic pressure thereon, and for causing contact between said first and second non-electrically conductive substrates in the presence of hydrostatic pressure thereon, producing said electrical bridging contact between said pair of conductors on the first non-electrically conductive substrate.
