Abstract

An actuator component for a keypad suitable for use with a mobile communication or a handheld device. The actuator component is formed from multiple materials and comprises a plurality of actuators, a sealing bead and a light guide. The sealing bead is formed from silicone rubber. When the keypad is installed the sealing bead is compressed against the mounting surface in the device and provides a seal for the keypad against environmental agents such as moisture, dust and/or electrostatic discharges.
