Abstract
A dome switch (12) of an electrically operated product (10) includes an electrically conductive dome switch member (30) having a central dimple (36) and a peripheral portion (38) that is secured by two retainers (42) which permit sliding alignment of the dome switch member. A switch actuator (44) of the dome switch (12) has an alignment button (46) received by the dimple (36) of the dome switch member (30) so as to provide sliding of the dome switch member on a circuit board (16) and thereby providing alignment with first and second contacts (18, 20) to provide effective switch closing.
