Abstract
Excess clearance provided between a multi-wide keytop and a rigid supporting housing layer is removed by provision of yieldable projections that extend upwardly beyond the housing layer and engage the movable leveling bar. The projections are formed integrally with an underlying dome sheet of elastomeric material and protrude through complementary openings formed through the housing layer.
