Pressure sensitive layers are disposed on respective resin films through electrodes to face each other, and include high conductivity flaky carbon particles and low conductivity amorphous-based carbon particles. The two kinds of carbon particles are bound together by a resin-system binder. Accordingly, when a pushing force is applied to the resin films, an average distance between the carbon particles is decreased to cause a tunnel conduction phenomenon, resulting in a decrease in conductive resistance between the electrodes. As a result, a pressure sensing property can be made gentle.

A membrane switch having a pair of flexible printed boards and a pair of contacts respectively disposed on said printed boards. The contacts are formed of powdered alloy of silver and palladium bounded by resinous material, and a conductive layer of silver powder is disposed between the flexible printed board and the contact. Preferably, the powdered alloy contains 50-97 weight percent silver and palladium in the remainder of weight percent.
