Solid product but problrems in connecting up

The isolator is a compact footprint, and seems robust. I have not run final commissioning and life tests on the DC to AC unit I have used it in yet but....
During assembly the triangular internal contact came loose and jammed the switch. Panic - I was putting the DC to AC power unit fout for its first filed test the next day! So I disassembled the switch and reassembled it correctly and all is fine now. It was lucky that I had a square headed screw driver from when I lived in Canada though!
