Earlier this school year my district purchased ten of your 4xAA battery holders with on/off switches (PN 830) for my physics classes. We just used them this week for the first time, and there appears to be a defect. The positive (red) wires pop off with normal handling. It appears from the technical drawings that the red wire is supposed to go around a post inside the case for strain relief, however in the units we have the red wire comes straight off the solder joint (which is very small) and so it doesn't take much wiggling to get them to pop off. They are heat sealed, so there is no easy way to open and fix them without damaging them. Is it possible to get these replaced? Thanks!
