Abstract
An improved button actuation assembly for activating a switch on hand held devices such as portable barcode readers has an improved structure that absorbs and dissipates the force exerted on the button. The improved structure thus protects the switch and the button actuation assembly itself from being damaged by excessive force such as from an impact shock caused by dropping or misuse.
Claims2
A button actuation assembly for activating a switch comprising:

- and
- a compressible button buffer provided between the button and the button retainer.
