US 9,058,941 B2 · Floating switch assemblies and methods for making the same

Abstract

Switch assemblies that mitigate stack up variations and methods of making the same are provided. The stack up variations are mitigated by embodiments that use a floating switch design. The floating switch design may eliminate height variations in the stack up by directly mounting an activation assembly to a support bracket. This ensures that the stack up height of the activation assembly and support bracket remain fixed, independent of a flexible printed circuit board (PCB) that may also be secured to the activation assembly. This way, regardless of the thickness of the flexible PCB and any height variations in solder used to secure the flexible PCB to the activation assembly, the stack up height of the activation assembly and support bracket remains fixed.

Dependent claims

An electronic device, comprising:

a bracket;
an activation assembly comprising:
a structural member fixed to the bracket;
a dome switch disposed on the structural member;
at least one terminal that extends away from an outer surface of the structural member;
and
a flexible printed circuit board that relays an electrical signal received from the at least one terminal when a switch event occurs, the flexible printed circuit board having a first side coupled to the bracket and to the at least one terminal.
