Emergency pull-wire switches

Emergency pull-wire switches are used on machines and plants which cannot be safeguarded by safety covers. In contrast to an Emergency-stop push button the emergency pull-wire switch can be actuated from any point along the wire. All emergency pull-wire switches conform with European standard EN ISO 13850 and IEC/EN 60947-5-5.

The emergency pull-wire switches have an integrated wire break monitoring function. If the emergency pull-wire switches are actuated or if the wire breaks, all NC contacts are opened and all NO contacts are closed. Most emergency pull-wire switches have a robust metal housing. A wide range of accessories is available for all product types.
