TRIGGER OPERATED ELECTRONIC DEVICE

摘要

A device particularly for use with a computer comprises a housing (13) for location at least partly between two fingers (14 and 15) of a hand (16) and an electronic circuit (17) mounted on a board (18) within the housing. The circuit includes a switch (19) responsive to pressure selectively to open and close an electronic circuit, and conductive elements (47) arranged on the board (18) mounting the electronic circuit (17). A first control element (20) is mounted with the housing and responsive to finger pressure such that pressure applied to the first control element (20) causes the element to operate the switch (19). The second control element (22) includes a flexible material mounted such that pressure applied to the flexible material in different directions and positions acts to change the electrical relationship between the conductive elements (47) on the board (18) and thereby vary an output signal from the electronic circuit.
