I am fairly sure than no matter how soft closing any door is, it will work any micro switch. Some answering/recording machines had, as an end of loop sensor, a micro switch that was worked by the tape having a double thickness at that point. And that was with 1970's technology. OK, as soon as possible, the move was made to a light bulb and a photocell, but the switches were sensitive enough to usually work at limits like that. They are sensitive little thingys, but in cases like these will need provision for adjustment.
For battery powering low current intermittent things (hijack warning) I was just looking at a card of watch batteries and wondering what to do with the unwanted size ones like the AG12 and 13 ones. There must be something that us modelers can do to usefully extract the energy from them before sending them to landfill.
