Keyboard device

A keyboard device comprising:

• a key top having an upper surface, an opposite, lower surface, and a plurality of first projections extending from the lower surface,
• wherein the key top is movable between a depressed position and a non-depressed position;
• a pair of link members, each including arms, each of which arms has an upper proximal portion attached to links rotatably coupled with the first plurality of projections of the key top, an opposing distal portion having teeth, and second projections extending inwardly from the arms;
• a support panel that is located below the key top, has a planar top surface and has a plurality of first through-holes, a plurality of second through-holes, a plurality of third through-holes, and a portion of the support panel extending between the second and third pluralities of through-holes;
• a housing between the support panel and the key top and between the pair of link members, said housing having a plurality of bases extending therefrom,
• wherein each of the link members is rotatably supported by the second projections being received above the support panel by the housing;
• a member above the support panel and below the key top having at least one through-hole formed therein over the plurality of first, second and third through-holes of the support panel, the member including a rubber operating member that is received within the housing and biases the key top into the non-depressed position;
• and
• a switch located between the support panel and the rubber operating member which is activated when the key top is in the depressed position,
• wherein the at least one through-hole of the member receives the plurality of bases of the housing therethrough, and the plurality of first through-holes of the support panel receives the bases of the housing therein, respectively, when the key top is in the depressed and non-depressed positions,
• wherein the at least one through-hole of the member receives the first projections of the key top therethrough, and the plurality of second through-holes of the support panel receives the first projections of the key top therein, without the first projections of the key top contacting the support panel, when the key top is in the depressed position, and
• wherein the at least one through-hole of the member receives the distal portions of the arms therethrough, and the plurality of third through-holes of the support panel receives the distal portions of the arms therein, without the distal portions of the arms contacting the support panel, but with the proximal portions of the arms contacting the portion of the support panel, when the key top is in the depressed position.
