Abstract
Abstract A resilient housing actuated multi-level housing switch comprises a compression sensitive circuit which is actuated by compressing a resilient housing. The compression sensitive circuit comprises a compression sensing device which produces an analog signal, an A to D converter, and a microprocessor. The microprocessor is programmed with algorithms to control the power levels of communication equipment and volume levels based on signals produced by compressing the compression sensing device.
