1 Basic Requirements

1.1 Scope and purpose This section provides three enable switch requirements. This section applies to the switch as an enabling device (see 10.9 GB 5226.1-2008 provisions) components used in the following cases Provide signals. 1) is energized, allowing the mechanical operation initiated by a separate start control, and 2) de-energized when. a) initiation stop function, and b) to prevent mechanical operation. Note 1. The control function is enabled in GB 5226.1-2008 is described in 9.2.6.3. Note 2. This section does not involve enabled device. This section does not apply to. --- Three for non-electrical control circuit enabling switch, for example, hydraulic, pneumatic; --- Not so with three mechanical devices can switch; --- Emergency brake (see GB/T 14048.14). 1.2 Normative references The following documents for the application of this document is essential.
