Abstract
A manually operable "bubble" button for an amusement device, such as an arcade game, includes inner and outer nested, generally cup-shaped members formed of suitable plastic material. The inner member has an annular flange which seats on an annular shoulder of the outer member to limit the depth of insertion so that the concave wall portions of the members are spaced apart. Circumferentially spaced ribs on the inner member engage the outer member to center the members and a locating tab on the inner member seats in a recess in the outer member to ensure proper relative orientation of the members. An indicium is disposed between the inner and outer members, preferably being fixed to the inner member, at least the outer member being substantially transparent to visible light so that the indicium can be seen therethrough. The members are fixed together adjacent to their open ends.
