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, 45 b). The or each button member ( 41 ) is movable with respect to its at least one fluid channel ( 450, 45 b) to cause an internal pressure change in the fluid channel ( 450, 45 b). 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. |
