Applies to electrical control circuit devices and switching elements with mechanical latching function, which are used to provide an emergency stop signal. Provides detailed specifications relating to the electrical and mechanical construction of such devices and their testing. This Standard is identical with and reproduced from IEC 60947-5-5:1997.

This section of IEC 60947-5 provides detailed specifications relating to the electrical and mechanical construction of emergency stop devices with mechanical latching function and to their testing.This standard is applicable to electrical control circuit devices and switching elements which are used to provide an emergency stop signal. Such devices may be either provided with their own enclosure, or installed according to the manufacturer's instructions.This standard does not apply to:– emergency stop devices for non-electrical control circuit, for example hydraulic, pneumatic;– emergency stop devices without mechanical latching function.An emergency stop device may also be used to provide an emergency switching off function (see annex A).
