A wireless telephone system comprises a base unit and a plurality of wireless handsets. At least one spring beam is cantilevered over a pivot point to exert an axial force between the first and second elements and the torque rate of the test joint can be varied by moving the pivot point to change the axial force. The switch device controls the control switch to be turned offon when the electric wave is received. The support structure extends generally upward and generally perpendicular relative to the generally horizontal platform.
