Patent Images
1. An input module comprising:
- an input button configured to receive lateral and rotational input from a user;
a shaft coupled to the input button;
an array of optical elements arranged around the shaft;
a sensing element configured to detect the rotational input from the input button using the array of optical elements;
a collapsible dome switch operable to collapse in response to the lateral input from the user; and
a shear plate positioned between the collapsible dome switch and an end of the shaft, wherein the shear plate;
is configured to transmit the lateral input from the input button to the switch; and
prevents the rotational input applied to the input button from being transmitted to the collapsible dome switch.

Abstract
One embodiment of the disclosure includes an input module. The input module includes a switch, a rotatable and translatable input member operably connected to the switch and configured to actuate the switch, and an electrical contact operably connected to the switch and in electrical communication with the input member. During operation, the electrical connection between the input member and the electrical contact is maintained during translation and rotation of the input member. The input module may be used with a variety of electronic devices and can be used by a user to provide input to those devices.
