Curved Keyboard Test Jig
Buttontester jig design

Project Brief:

Design a test jig for a handheld device with a curved keyboard.

The client had requested that we designed a manually operated test jig that depressed all the keys in turn. Each key had to be depressed individually with a given force. Keys could not be depressed at the same time. The equipment would need to be capable of very rapidly cycling though the entire keyboard very rapidly (in the region of 2 seconds). The tested devices also needed to be rapidly exchanged to allow for a large quantity of devices to be tested quickly and efficiently.


The jigs were manufactured to Alphatech’s design and worked flawlessly without modification.



The client’s reaction after the first jig was manufactured and tested was ‘An excellent piece of engineering design’.
