ABSTRACT:
A pushbutton and cover combination for operating an electronic switching device, such as a telephone or keypad. The cover defines a number of button receiving apertures extending therethrough. Each button comprises a body having a first part which provides a contact surface and a second part which is slidably received through an individual one of the apertures, so that the contact surface of the button is accessible from a first side of the cover. Latches on the second part of the button body are cooperable with the cover so that the button is held captive in the cover, with the second part of the body being operable to move slidably within the aperture, for engaging a flexible barrier layer and operating the electronic switching device on an underlying circuit board. The subassembly of the cover with the captive buttons is removable intact from the circuit board and flexible barrier layer of the electronic switching device. After removal of the subassembly, the latches are accessible and the buttons are removable from the cover.
