Dear Peter, BG stands for Berufsgenossenschaften (don't ask*). I think the certification mark "BG" has a rather overweight ... uh thinness challenged "i" to the left of it. The interlock was certified by the BG Institute for occupational safety in Germany. You may also see IEC/EN 60947-5-1 (chapter 3) written on the switch. This signifies that it is a positive opening device.
