An electronic device (100) that has an housing assembly and electrical circuit therein includes a first housing portion (116), a second housing portion (118) coupled to the first housing portion (116), and a cam assembly (102) rotationally coupling the first and second housing portions (116, 118). The cam assembly (102) includes a cam (220), a cam follower (205), and a spring (224). The spring (224) resiliently biases the cam (220) and the cam follower (205) into engagement. At least one of the cam (220) and cam follower (205) is depressible within one of the first and second housing portions (116, 118) for permitting their assembly.
