A button assembly (100) that includes a flexible electronic circuit (105) having a first side (110) and a second side (115). The button assembly also can include a biometric sensor (100) mounted to the first side of the flexible electronic circuit. Further, a switch (200) can be positioned at least proximate to the second side of the flexible electronic circuit. A stiffening member (305) can be attached to the first side or the second side of the flexible electronic circuit. The biometric sensor can be operable between a first position and a second position to effectuate opening or closing of the switch. The button assembly can operate the biometric sensor between the first and second positions utilizing pivotal, translational, and/or rotational movement.
