A case for electronic devices having buttons may include button mechanisms that allow the case slide over an electronic device without impacting the buttons. Each button mechanism may include a sheet spring that biases the button mechanism away from the buttons. When a user presses the button mechanism, the button mechanism may transmit force from the user to one of the buttons and actuate that button. One type of button mechanism may transmit force that actuates a single push-button. A second type of button mechanism may transmit forces that actuate a rocker switch with two actuation modes such as a volume rocker with a volume up mode and a volume down mode. The button mechanisms may be configured to provide tactile feedback to the user that is similar to the tactile feedback of the electronic device's buttons when the electronic device is not mounted in the case.

1. A removable case for an electronic device that has a button, comprising: a housing into which the electronic device is removably inserted, wherein the housing has portions defining a hole;a button mechanism mounted in the hole, wherein the button mechanism has a given portion that bears against the button in the electronic device when the button mechanism is actuated by a user; anda sheet spring that biases the button mechanism away from the button in the electronic device, wherein the housing has inner surface regions that surround the hole and wherein, when the button mechanism is not being actuated by the user, the given portion of the button mechanism is approximately flush with the inner surface regions of the housing. 2. The removable case defined in claim 1 wherein the button mechanism comprises a first member having a first press-fit engagement feature and a second member having a second press-fit engagement feature, wherein the first and second press-fit engagement features are coupled together. 3. The removable case defined in claim 1 wherein the button mechanism comprises a retaining member that has a female press-fit structure and an external member that has a male press-fit structure and wherein the female and male press-fit structures are connected together through the hole. 4. The removable case defined in claim 3 wherein the retaining member comprises a substantially rectangular metal retaining member and wherein the female press-fit structure comprises a substantially rectangular protrusion from the metal retaining member that defines a cavity. 5. The removable case defined in claim 4 wherein the external member comprises a substantially rectangular metal external member and wherein the male press-fit structure comprises a substantially rectangular protrusion from the metal external member that fits within the cavity. 6. The removable case defined in claim 1 wherein the housing has a lip that extends at least partly into the hole and wherein the lip bears against portions of the button mechanism to hold the button mechanism in the hole. 7. The removable case defined in claim 1 wherein the sheet spring has a U-shaped edge profile and wherein the sheet spring has center portions that bear against the housing. 8. The removable case defined in claim 1 wherein the sheet spring has a U-shaped edge profile and wherein the sheet spring has center portions that bear against the button mechanism. 9. The removable case defined in claim 1 wherein the sheet spring has a W-shaped edge profile and wherein the sheet spring has end portions that bear against the housing. 10. The removable case defined in claim 1 wherein the sheet spring has a W-shaped edge profile and wherein the sheet spring has end portions that bear against the button mechanism. 11. The removable case defined in claim 1 wherein the button mechanism comprises a plurality of planar stainless steel members. 12. A removable case for an electronic device that has a rocker button having a first portion and a second portion, comprising: a housing into which the electronic device is removably inserted, wherein the housing has portions defining a hole;a pivoting button mechanism mounted in the hole, wherein the pivoting button mechanism bears against one of the first and second portions of the rocker button in the electronic device when the pivoting button mechanism is actuated by a user; anda spring that biases the pivoting button mechanism away from the button in the electronic device such that the pivoting button mechanism is retracted into the housing and does not scrape against the electronic device as the electronic device is removably inserted into the housing. 13. The removable case defined in claim 12 wherein the spring comprises a sheet spring member that has a W-shaped edge profile. 14. The removable case defined in claim 12 wherein the housing comprises first and second stop members and a fulcrum member and wherein the first and second stop members and the fulcrum member extend into the hole. 15. The removable case defined in claim 14 wherein the pivoting button mechanism comprises a member that, when the pivoting button mechanism is actuated by the user, bears against the fulcrum member so that the pivoting button mechanism pivots about the fulcrum member and bears against one of the first and second portions of the rocker button in the electronic device when the pivoting button mechanism is actuated by the user. 16. The removable case defined claim 12 wherein the housing has an elongated rectangular shape with an opening at one end that is configured so that the electronic device is removably inserted into the housing by sliding the electronic device into the housing through the opening. 17. A removable case for an electronic device that has a button, comprising: a housing into which the electronic device is removably inserted, wherein the housing has portions defining a hole; anda button mechanism mounted in the hole, wherein the button mechanism has given portions that bear against the button in the electronic device when the button mechanism is actuated by a user, wherein the button mechanism comprises first and second opposing metal plates connected together through the hole, wherein the housing has surface regions that lie in a first plane, that surround the hole, and that are adjacent to the electronic device when the electronic device is inserted into the housing, wherein, when the button mechanism is not being actuated by the user, the given portions of the button mechanism lie in a second plane, and wherein the first plane is between the second plane and the electronic device, when the electronic device is being removably inserted into the housing. 18. The removable case defined in claim 17 wherein the first and second metal plates each comprise a press-fit engagement member. 19. The removable case defined in claim 17 wherein the button in the electronic device is a rocker button having a first portion and a second portion, wherein the button mechanism comprises a pivoting button mechanism that bears against one of the first and second portions of the rocker button in the electronic device when the pivoting button mechanism is actuated by the user, and wherein the first metal plate comprises an external surface and wherein the second metal plate comprises a surface that bears against the rocker button in the electronic device. 20. The removable case defined in claim 17 further comprising a spring having a W-shaped edge profile that biases the button mechanism away from the button in the electronic device.
