适用范围：This part of IEC 60947 specifies requirements for three-position enabling switches.These switches are used as components of enabling devices described in 10.9 ofIEC 60204-1 to provide signals that,a) when activated, allow machine operation to be initiated by a separate start control, andb) when de-activated,i) initiate a stop function, andii) prevent initiation of machine operation.NOTE 1 The enabling control function is described in 9.2.6.3 of IEC 60204-1.NOTE 2 This standard does not deal with enabling devices.This standard does not apply to:− three-position enabling switches for non-electrical control circuits, for example hydraulic, pneumatic;− enabling switches without three-position mechanism;− emergency stop devices (see IEC 60947-5-5).
