display 280 is shown immediately below top cover 278 the sides of lcd 280 are shown as comprising a series of electrical contacts which serve to activate the various segments of the display below the lcd is a diffuser 282 which is preferably molded in a one piece structure from a generally transparent plastic diffuser 282 serves to backlight and support the lcd diffuser 282 has a pair of opposing slots which lie along the length of the lcd electrical contacts thereby leaving those contacts exposed lying below diffuser 282 is an electronic timer module 288 which includes the electronic components of timer assembly 214 and the battery to operate them a pair of electronic contact strips 290 lie along the surface of timer module 288 corresponding in position to the lcd electrical contacts advantageously from a manufacturing standpoint a pair of 34 zebra 34 pads 288 are provided for placement between strips 290 and the lcd electrical contacts zebra pads 288 are constructed as a composite of small blocks of insulating material and conductive material and are capable of carrying current from pads 290 to the lcd without mechanical connections zebra pads 288 extend through slots 284 and are held in place by the boundaries thereof as indicated above it is also possible to provide a 34 1 button 34 timer assembly although not illustrated the function of a 1 button embodiment will be readily understood from the disclosure set forth above unlike the 2 button and 3 button timer assemblies it is currently contemplated that it might in some instances be less important to provide access to multiple historical events rather it may be adequate in some circumstances to provide a timer.
