Abstract

A SWITCH FOR USE IN A KEYBOARD OR KEYPAD COMPRISES A BALL-SHAPED INTERFACE MEMBER (10) WHICH INTERACTS WITH ELECTRICAL CONTACT (13,32) IN RESPONSE TO FINGER CONTACT. THE ELECTRICAL CONTACTS CONSIST OF A PAIR OF NESTED BOWL-SHAPED CONTACT MEMBERS (13, 32) WHICH CONFORM GENERALLY TO THE SHAPE OF THE SURFACE PORTION (16) OF THE BALL MEMBER (10) THAT INTERACTS THEREWITH. A RESILIENT SUPPORT MEMBER (11) SUSPENDS THE INTERFACE MEMBER (10) INA NEUTRAL POSITION IN WHICH IT DOES NOT OPERATE THE CONTACTS AND ALLOWS THE INTERFACE MEMBER TO MOVE BOTH VERTICALLY AND LATERALLY TO OPERATE THE CONTACTS (13, 32). A KEYSTROKE IS THEREBY ACHIEVABLE IRRESPECTIVE OF THE DIRECTION IN WHICH THE INTERFACE MEMBER (10) IS PUSHED BY THE OPERATOR'S FINGER.
