Abstract
A keyboard has keys, or buttons, having guide projections which, when the keys are pushed from an operating side, are shoved along guide plates, with motion being restricted by a locator, the locator having two stops which restrict the motion of the keys between the two stops and with a switch being activated being ON and OFF by the key moving within these limits. This provides a very flat keyboard which is economical to manufacture.
