An actuator button is mounted in a housing by a cantilevered beam fixedly attached to the intermediate portion of a torsion beam. The ends of the torsion beam are nonrotatably fixed with respect to the housing. The actuator button is maintained at a normal, spaced-apart position with respect to a switch positioned within the housing. Movement of the actuator toward the switch induces bending stress in the cantilevered beam and torsional stress in torsion beam. The actuator button arrangement permits direct, vertical insertion of the actuator button into the housing, does not require any secondary assembly operations, and has a unitary construction. |
