When a printed circuit board is loaded onto a fixture having two fixed locating pins, and the board is flexed such as caused by inserting a component on the board, one or the other of the locating pins is subject to breakage and damage in a relatively short period of time. This problem can be overcome, as shown in the drawings, by use of a movable pin 1 in combination with a fixed pin 2. The theory of operation is best understood from Fig. 2. When a printed circuit card 3 is placed over locating pins 1 and 2, flexure of the card to produce a displacement Dy causes the pin to move from its normal position shown in dotted lines to the position shown in full lines over a cor (Image Omitted) responding displacement Dx.
