Abstract
A switch array (10) comprising a housing (12) having a front face (14), a rear face (16), and a number of through bores (18) extending from the front face to the rear face; a resilient switch card (30) having a front face (34) directed towards the rear face of the housing, a rear face (36) directed away from the housing, and a number of contact areas (38) on the front face associated with each through bore, wherein the number and position of the contact areas associated with each through bore is identical; a switch cap (20) slidably mounted in, and removable from, one of the through bores, the switch cap having a front face (22) adjacent the front face of the housing, a rear face (24) adjacent the rear face of the housing, and one or more pins (28) projecting from the rear face of the switch cap, wherein the number and position of the or each pin is predetermined, and wherein the or each pin can exert pressure on one of the contact areas associated with the through bore on pushing the switch cap from a rest position; an electrical circuit board (32) mounted on the rear face of the resilient switch card and having an electrical circuit associated with each contact area such that when pressure is exerted on one of the contact areas, an electrical signal is generated in the associated electrical circuit. Using two or more switch caps with unique numbers and positions for the pins allows selection of the switch caps by an operator, and the relative positions of the switch caps to be selected.
