The switch assembly includes a switch member, a housing and a support member. The housing is mounted on a printed circuit board and the switch member is attached to the housing. The support member is mounted on the surface of the printed circuit board adjacent to a back surface of the switch member. ## Claims ### Claim 1 A switch assembly, comprising: a switch member; a housing, wherein the switch member is attached to the housing; and a support member positioned adjacent to a back surface of the switch member. ### Claim 2 (depends on 1) The switch assembly of claim 1, wherein the surface of the switch member adjacent to the support member contacts the support member when the switch member is activated. ### Claim 3 (depends on 1) The switch assembly of claim 1, wherein the switch member comprises a pushbutton switch moveable within the switch member for activation. ### Claim 4 (depends on 3) The switch assembly of claim 3, wherein the switch member is activated by application of a pressing force to the pushbutton at a first surface of the switch member and the surface opposite the first surface contacts the support member when the switch member is activated. ### Claim 5 (depends on 4) The switch assembly of claim 4, wherein the support member acts to impede movement of the switch member in the direction of movement of the pressing force. ### Claim 6 (depends on 1) The switch assembly of claim 1, wherein the support member is formed of plastic. ### Claim 7 (depends on 1) The switch assembly of claim 1, wherein the housing has sidewalls that extend beyond a back surface of the switch member. ### Claim 8 (depends on 1) The switch assembly of claim 1, wherein the support member comprises at least one fastener to mount the support member on a surface of a printed circuit board. ### Claim 9 (depends on 8) The switch assembly of claim 8, wherein the at least one fastener limits movement of the support member in at least one of the direction of movement of the pushbutton switch and a generally perpendicular movement to the direction of movement of the pushbutton switch when the switch is activated. ### Claim 10 (depends on 1) The switch assembly of claim 1, wherein the support member comprises a rectangular base and a T-shaped portion extending upward from the rectangular base. ### Claim 11 (depends on 10) The switch assembly of claim 10, wherein the T-shaped portion of the support member contacts the surface of the switch member to limit the movement of the switch member in the direction of movement of the pushbutton switch to the distance between the surface of the switch member adjacent to the support member and the T-shaped portion of the support member. ### Claim 12 (depends on 10) The switch assembly of claim 10, wherein the T-shaped portion of the support member is positioned between the sidewalls of the housing adjacent to the surface of the switch member. ### Claim 13 An electronic device, comprising: a printed circuit board; a switch assembly comprising a switch member, a housing, wherein the housing is mounted on the printed circuit board and the switch member is attached to the housing; and a support member mounted on the surface of the printed circuit board adjacent to a back surface of the switch member. ### Claim 14 (depends on 13) The electronic device of claim 13, wherein the surface of the switch member adjacent to the support member contacts the support member when the switch member is activated. ### Claim 15 (depends on 13) The electronic device of claim 13, wherein the switch member comprises a pushbutton switch moveable within the switch member for activation. ### Claim 16 (depends on 15) The electronic device of claim 15, wherein the switch member is activated by application of a pressing force to the pushbutton at a first surface of the switch member and the surface opposite the first surface contacts the support member when the switch member is activated. ### Claim 17 The electronic device of claim, 16 wherein the support member acts to impede movement of the switch member in the direction of movement of the pressing force. ### Claim 18 (depends on 13) The electronic device of claim 13, wherein the support member is formed of plastic. ### Claim 19 (depends on 13) The electronic device of claim 13, wherein the housing has sidewalls that extend beyond a back surface of the switch member. ### Claim 20 (depends on 19) The electronic device of claim 19, wherein the sidewalls of the housing are provided with a plurality of support elements contacting the printed circuit board. ### Claim 21 (depends on 13) The electronic device of claim 13, wherein the support member comprises at least one fastener to mount the support member on the surface of the printed circuit board. ### Claim 22 (depends on 21) The electronic device of claim 21, wherein the at least one fastener limits movement of the support member in at least one of the direction of movement of the pushbutton switch and a generally perpendicular movement to the direction of movement of the pushbutton switch when the switch is activated. ### Claim 23 (depends on 13) The electronic device of claim 13, wherein the support member comprises a rectangular base and a T-shaped portion extending upward from the rectangular base. ### Claim 24 (depends on 23) The electronic device of claim 23 wherein the T-shaped portion of the support member contacts the surface of the switch member to limit the movement of the switch member in the direction of movement of the pushbutton switch to the distance between the surface of the switch member adjacent to the support member and the T-shaped portion of the support member. ### Claim 25 (depends on 23) The electronic device of claim 23, wherein the T-shaped portion of the support member is positioned between the sidewalls of the housing adjacent to the surface of the switch member. ### Claim 26 (depends on 13) The electronic device of claim 13, wherein a plurality of fasteners are used to mount the housing on the surface of the printed circuit board. ### Claim 27 A set top box, comprising: a casing; a printed circuit board, wherein a wall of the casing abuts a portion of a side of the printed circuit board; and a switch assembly comprising a switch member, a housing, wherein the housing is mounted on the printed circuit board and the switch member is attached to the housing; and a support member mounted on the surface of the printed circuit board adjacent to a back surface of the switch member.
