The design of these pull cord switches considerates heavy duty service. Enclosures made of most stable, impact resistant, thick walled glass fibre-reinforced polyester (BMC) or optional of cast iron are the best guarantors for long years of reliable service. Bothtypes are at least IP67-protected (water- and dust proof).
Pull cord switches of this type are for single-sided rope mounting with a maximum rope length of 1 x 40 metres. Pulling on this rope operates all contacts via snap action mechanism. Simultaneously with this operation the latching is being effected automatically. The actuation arm indicates the 3 different switch positions: Neutral, manually actuated or rope slack. In neutral position and at correct rope length the lever stands vertical. In actuated position, after pulling the rope, the lever rests in its manually actuated position. Reset by manual release. In the position “rope slack” the lever is turned away from the pullcord by the internal spring and the contacts are also commutated. This complies to the standard EN 60947-5-5 (automatic emergency stop demand at rope break).
These switches will be equipped with up to 2 micro switches. Each micro switch incorporates either 1NC plus 1NO contact or alternatively 2NC‘s. The contacts are made of silver, a gold coating is optional. Each micro switch is certified by VDE and CCC and is bearing their signs. The switches are also approved to bear the Eurasian EAC sign.
Malfunctions and unwanted stops caused by vibrations or thermical tensions within the ropes are unlikely due to the unrivalled large rope travel (34 mm, longitudinally drawn) as well as the large rope tension (>40 N) necessary for switching.
Guarantors for an extended, reliable life time are most important details like sealing rings protecting the shafts, an extra hard rubber gasket in the lid, shafts and screws made of stainless steel.
2 different versions for the mounting of the rope to the left or to the right are available.
