Rotary Cam Switch GSWF Leonard Engineering Gmbh 

Leonard rotary  cam switches GSWF are cased in housings made of cast aluminum and fitted out with mechanic switching elements. The technical data of all available switching elements . The rotary cam switches GSWF are normally available with 1 to 6 switching element. If the rotary cam switch GSWFs is built with a worm gear unit, it is available up to 12 switching element. For a switch including a worm gear unit the cam shaft (spindle) comes out on both sides of the housing. Otherwise the cam shaft is only on one side projected. The cam shaft is mounted in deep groove ball bearings and maintenance-free.

To actuate  individual switching elements the cam shaft is fitted with cam disk sets in a pitch of 20 mm. Each cam disk set consists of the components. The infinitely adjustable cam disk sets, which run almost entirely free from unbalance by virtue of their special design, are individually tensioned by disc springs. This tension is such that all cam disk sets can be adjusted when the clamp nut is slackened. After setting all the cam disk sets the complete adjustment can be checked on start up for trial operation. Only after all switching adjustments have been tested, the clamp nut is tightened against the disc spring. All cam disk sets are positively located in the position set.
