Abstract
It consists of a body (1) having a sliding key (2) that may activate some side actuators (7, 8), and a central actuator (9), which act over the upper base of the cones (13) of a membrane (14) triggering a determined part of a circuit (15). For this purpose, there are at least two fixed guides (5, 6) between the key (2) and the actuators (7, 8, 9) to guide the sliding of a runner (3) rigidly joined to the key (2) that serves to activate the actuators (7, 8, 9). The runner (3) includes a sliding strip (17) having pivots (18) housed in some crossed slots (19, 20) formed in the fixed guides (5, 6), permitting the guided displacements of the key (2) with the runner (3) in two perpendicular directions to activate the mentioned actuators (7, 8, 9).
Claims4
—A SLIDING MEMBRANE SWITCH that includes a body (1) with a key (2) destined to trigger some actuators (7, 8, 9) which include two aligned arms (11, 12) emerging oppositely from a swinging body (10), whose ends respectively act over the upper base of the cones (13) of a contact membrane (14), triggering a determined part of a circuit (15), characterised because the switch includes a strip and at least two fixed guides (5, 6) arranged between said key (2) and the corresponding actuators (7, 8, 9), which serve to guide the sliding movement of a runner (3) rigidly joined to the key (2), said runner (3) being destined to activate the mentioned actuators (7, 8, 9), whose arms (11, 12) are arranged in opposite directions.
—A SLIDING MEMBRANE SWITCH, according to claim 1, characterised in that the runner (3) consists of a sliding strip (17) having, at its ends, some pivots (18) extended upwards and respectively housed in crossed slots (19, 20) formed in the fixed guides (5, 6), allowing the guided displacement of the key (2) with the runner (3) in two perpendicular directions to activate the mentioned actuators (7, 8, 9).
—A SLIDING MEMBRANE SWITCH, according to claim 1, characterised in that it includes two side actuators (7, 8) and a central actuator (9), said side actuators (7, 8) being arranged with their arms (11, 12) parallel to each other and perpendicular with respect to the arms (11, 12) of the central actuator (9).
—A SLIDING MEMBRANE SWITCH, according to claim 3, characterised in that the central actuator (9) includes a pivot (21) emerging upwards and which is inserted in a rotary manner in a lower housing (22) of the runner (3), such that the displacement of said runner (3) provokes the swinging movement of the central actuator (9) triggering a cone (13) of the contact membrane (14).
