CA 2652356
A keypad assembly for a wireless device is provided. The keypad assembly comprises a circuit board, a keypad portion, a light guide, and at least one friction device. The keypad portion has a number of keys for physical actuation, each of the keys having an actuator post attached to a back side of the key. The circuit board has one or more electrical switches, the electrical switches corresponding to the keys of the keypad. The light guide is located behind the keypad portion and in front of the circuit board. The light guide has a number of holes formed therein. The holes provide paths for respective actuator posts of the keys to travel through to contact the respective electrical switches on the circuit board. The at least one friction device is located in at least one of the holes of the light guide. The friction device provides a physical barrier limiting movement of the actuator post in a direction normal to the direction of actuation and the friction device applies friction to the side of the actuator post, thereby resisting movement of the actuator post in the direction of actuation.
