ABSTRACT:
A switch for a card reader assembly forming a portion of a radio transceiver. The switch is operative responsive to positioning of a card member at a support position of the card reader assembly. The switch is operative to move out of a first switch position and into a second switch position responsive to actuation forces exerted upon the switch by the card member. The actuation forces are exerted by the card member to position the switch at the second switch position only when the card member is positioned at the support position. A lever arm of the switch includes a force receiving surface for receiving actuation forces generated by the card member when positioned thereagainst. Application of the actuation forces generates twisting moments to cause pivotal movement of the lever arm about a pivot arm.
