p 1 p 2 p 3 p 4 the beams 22 32 are then spot welded together adjacent the first support surfaces 24 34 and second support surfaces 28 38 referring to fig3 the gages g 1 and g 2 are spaced the same distance apart as gages g 3 and g 4 each pair likewise being the same distance from the adjacent support surface 24 28 the deflecting surface 26 defining the deflecting portion of sensing beam 22 the deflecting surface 36 of the support beam 32 is recessed only sufficiently to accommodate deflection of the sensing beam 22 the surface 36 being arched to minimize its own deflection the thickness of the support beam 32 from the deflecting surface 36 to the opposed outside surface of the beam 32 ranges from 0 0110 inch to 0 0095 inch while the thickness of the opposed portion of the sensing beam 22 is uniform at 0 0100 inch the outside dimension of the probe 12 across beams 22 32 is 0 026 inch in the undeflected state the expected deflection is about 0 001 inch yielding an outside dimension of 0 025 inch in the deflected state thus when the probe 12 is inserted in a socket it will simulate a 0 025 inch square post the first support surfaces 24 34 extend beyond base 14 so that the beam deflection is limited to where needed the contact point lying in the center of the deflecting portion of sensing beam 22 which is defined.
