Rotary Cam Switch LNSE Leonard Engineering Gmbh

Leonard rotary  cam switches LNSE (see figure 1.6.1) are cased in housings made of cast aluminum and fitted out with mechanic switching elements. The technical data of all available switching elements are listed in figure 1.0.1. The rotary cam switches LNSE are normally available with 3, 6, 9 and 12 switching elements. The cam shaft (spindle) comes out on both sides of the housing so that several switches can be coupled together. The second end of the shaft, which is normally unused, is protected by a safety cover. The cam shaft is mounted in two deep groove ball bearings and maintenance-free.

To actuate the individual switching elements the cam shaft is fitted with cam disk sets in a pitch of 30 mm. Each cam disk set consists of the components listed in figure 1.6.2. The 180  cam rings, made of wear-resistant plastic, are mounted on the carrier disk, made of die-cast aluminum, by two screws and two clamp pieces. The two screws can be slightly slackened in order to turn the cam ring to any required position. The carrier disks have an angular scale of 360  with a graduation of 2  , though a precise switching angle resolution is provided.
