second conductive surface 20b the key module 11 includes mechanisms to effect the lifting of the fly plate 15 from the pad card 13 and to effect the downward thrust of stem 31 to effect actuation of the ohmic switch 20 the key module 11 is constructed to provide three distinctive force levels which resist the downward depression of the associated keybutton 35 a first low force level is provided to resist movement of the keybutton 35 downward through a first small initial distance called the pretravel distance this provides a tactile input to the operator that the keybutton 35 is moving downward the operator further knows that key actuation will not occur during movement through this initial distance after the pretravel distance has been traversed further downward motion of the keybutton 35 is met with greater resistive force indicating to the operator that key actuation will take place during this movement it is during this movement of the keybutton 35 that the fly plate 15 moves from the pad card 13 during normal typing once key actuation has taken place the operator releases the key and strikes further keybuttons to effect further printing however for example where it is desirous to have repeated printing of the same symbol the keybutton 35 is moved still further downward to thereby effect closure of the ohmic switch 20 this further downward motion is resisted by a third level of force the mechanisms which effect the various resistant forces and which cause actuation of the key module 11 will now be described referring now to fig2 of the drawing a perspective sectioned view of a multiple switch key module 11 in its unactuated position is depicted initial operator depression of the keybutton 35 effects downward motion of.
