At least one post extends from the button and through an opening in the partition and is fastened to the partition for mounting the button to the partition for pivotal movement which is limited by the engagement of the hook with the ledge. A membrane switch is mounted on the partition, and a bumper extends from the button for engaging the membrane of the switch to activate same. The bumper is fabricated from a silicone rubber to minimize the effects of relatively large pushing forces acting on the button and to enable the assembly to be used in relatively low temperature environments.
