ABSTRACT:
A pressure actuated switching device is made by applying at least a first layer of fluid conductive polymeric coating material to a surface of a sheet of green rubber material. The conductive polymeric coating is solidified to form an electrode, and the sheet of green rubber material is vulcanized. Two strips of green rubber may be simultaneously processed and then joined such that the respective layers of conductive coating are in spaced apart opposing relationship. The conductive polymeric coating may optionally be formulated with green rubber. Optionally, a blowing agent may be included in the conductive coating formulation so as to provide a cellular polymeric foam piezoresistive material from which the electrode is constructed. The green rubber sheets may be processed by a continuous rotary method or by a linear method using a clamping press having opening and closing dies for heating and joining the strips of green rubber.
