A computer keyboard having membrane switches activated by finger touch keys supported by an upper resilient layer of the membrane circuit board. The keys have a rigid projection fixedly secured to the finger touch part of the key. The key is depressable against the resiliency of the upper layer to make circuit contact. The key is guided during movement and has a short travel distance as well as very light touch for circuit activation. The keyboard addresses the problem of keyboard related repetitive strain injuries (RSl's).
