Abstract: An earthquake escape light system having several different triggering systems. In one system vibrations are sensed as several steel balls move between two plates with the upper plate being connected to an upright member. At the lower end of this upright member is a steel ball normally electrically insulated from a lower conducting surface. Vibrations will cause the steel lower ball to contact the lower conducting surface and complete an electrical path to a light source. Alternately, the upper plate may have an arm with a hook end attached to it. This end restrains a pivotally mounted tube with mercury within from completing an electric circuit to a light source. When vibrations occur the hook comes off to complete the circuit. In another embodiment two magnets normally equally attract the free end of a electrically connected spring. When this end is subject to vibrations one of the magnets attracts it to complete a circuit to a light source.
