ABSTRACT:
The specification describes a device termed a silent obturator which is in the form of a flexible strip having at least one mounting hole at one end portion at least and supported in bowed or arcuate configuration between two supports, one of which is movable toward the other and which carries a "moveable" contact member near but not at the mid-point thereof whereby motion of one support relative to the other causes outward or inward deflection of the obturator relative to a line between the supports in such manner as to displace the contact member toward the fixed support in one coordinate direction and away from the line between said supports in another coordinate direction effectively providing a resultant path of motion at an angle to the line between said supports which, when said moveable contact member is placed in spaced association with a "fixed" contact member relatively fixed in space provides a contact action therewith which is substantially tangential relative to the bow or curve of the obturator thus effectively eliminating contact noise thereby to achieve a relay action which is silent.
