Electronic personal injury protection device for powered saws, has contactless sensor(s) for detecting operator's electrical smog radiation field with/without threshold switch, and shut-off device

摘要

The electronic personal injury protection device has at least one contactless sensor (12) for detection of the operator's electrical smog radiation field with or without a threshold switch and at least one shut-off arrangement. The contactless sensor is subjected to several input potentials in succession by several sensing elements (14).
