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 year reliable service. Both types areat least IP67-protected (water- and dust proof). Pull cord switches of this type are for double-sided rope mounting with a maximum rope length of 2 x 50metres. Pulling on one of these ropes operates all contacts via snap action mechanism independent on the direction of pulling. Simultaneously with this operation the latching is being effected automatically.
The status (operated/not operated) as well as the direction from where the switch has been operated is indicated by the position of the latched actuation lever. The direct opening system (positive drive) forces the snap action NC contacts into open positionunder all circumstances. These switches will be equipped with up to 4 micro switches. Each micro switch incorporates either 1NC plus 1NO contact or alternatively 2NC‘s. They commutate independent on the direction of pull cord actuation.
The contacts are made of silver, a gold coating is optional. The contact surfaces are wiping: with every actuation,they are cleaning themselves.
Each micro switch is certified by VDE and CCC and is bearingtheir signs. The switches are approved also to bear the Eurasian EAC sign. Unrivalled long pull cord travel and the high actuation force prevent unwanted stops caused by solids fallingonto thepull cord. 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.
