An apparatus for actuating one or more functions on a remote electronic device comprises one or more button members (41) provided within a housing having no electronic components, each button member (41) being associated with at least one fluid channel (45a, 45b). A remote conversion means is also provided which is associated with the or each fluid channel (450, 45b). The or each button member (41) is movable with respect to its at least one fluid channel (450, 45b) to cause an internal pressure change in the fluid channel (450, 45b). The remote conversion means can detect any pressure change in the fluid channels to thereby produce an electrical signal for actuating an appropriate function on the remote electronic device. |
