Abstract
A gravity responsive attitude switch containing electrical contacts separated by a gap, the switch containing a bead liquid and a carrier liquid, the two liquids being immiscible and having different electric resistivity values, where the liquid bead may be disposed between the contacts by properly positioning the switch. The contacts are connected in an electronic circuit which senses the difference in resistivity dependent on whether the bead liquid or the carrier liquid is bridging the gap between the contacts, which in turn determines whether an operative electric circuit is opened or closed.
