CAPACITIVE TOUCH INTERFACE ASSEMBLY

摘要

A display assembly includes a transparent cover piece (62), a display shroud (48; 248) having a contact structure (74; 274) arranged to face the transparent cover piece (62), an interface subassembly (32; 232) mounted on the display shroud (48; 248), an electronics board shroud (44) having a support member (82) and a connection feature (84), and a biasing member (46) operably engaged between the display shroud (48; 248) and the electronics board shroud (44). The connection feature (84) mechanically connects the electronics board shroud (44) to the display shroud (48; 248) while permitting axial displacement and rotation therebetween. The biasing member (46) rests on the support member (82) of the electronics board shroud (44), and the biasing member (46) is configured to urge the contact structure (74; 274) of the display shroud (48; 248) into physical contact with the transparent cover piece (62). The interface subassembly (32; 232) includes a display circuit (36) for providing a digital display and a touch circuit (34) for providing touch actuation at or near the digital display through the transparent cover piece (62).
