  • Patent number: 5664668
    Abstract: A tactile button (10) for activating a tact switch disposed on electronic circuitry enclosed within a housing element (102) having a shoulder slot (106). The shoulder slot (106) is integrally disposed with a shoulder ledge (108) with two pivot slots (110,112) and an underside flange (114). The shoulder member (104) couples to the shoulder slot (106) and comprises an actuating stub (202), a second latch (204), and two pivot protrusions (208,208). The tact switch is activated by the actuating stub (202) when depressing on an outer surface (216) of the shoulder member (104) and movement of the shoulder member (104) is restricted to an angular direction (304) that pivots on the pivot slots (110,112). In an alternate embodiment, a portable electronic device (40) has a left tactile button (402) and a right tactile button (404) and inadvertent activation of either tactile button is prevented because activation of either tactile button (402,404) is not laterally but from a top portion of the outer surface (216).
