TREAD PRESSURE MAT

摘要

PROBLEM TO BE SOLVED: To surely turn on when a tread pressure mat is treaded by a human and prevent turning to an ON-state when being treaded by an animal other than the human. SOLUTION: A pair of pressure continuity members G is connected in series with a conductor 3 at prescribed interval S to constitute a tread pressure switch unit U which turns on when a pair of pressure continuity members G is treaded at the same time. Many tread pressure switch units U are arranged on a plane so as to be connected in parallel between a first wiring 4 and a second wiring 5 forming plus and minus sides.
