  • Electronic device with switch and pivotable actuator assembly
    Patent number: 5749457
    Abstract: An electronic device (100) includes an internally mounted circuit substrate (110) having a surface (111) with mounted electrical components (130), including a flat switch (132) having a direction of actuation (201) substantially perpendicular to the surface. The electronic device (100) includes an actuator button (150) with an externally accessible user interface portion (151) and an internally positioned actuator member (155). The actuator member (155) is pivotable from a first position adjacent to the switch (132), to a second position engaging and actuating the switch (132) when the user interface portion (151) is depressed. Preferably, the actuator button (150) is attached to a device housing member (121, 122) using an integrally formed shaft (180) that provides a spring bias return force for the button (150) when depressed.
