Industrial Controllers Technical Documentation The lever switches in Figure 1 – types S41 to S45 – are switches, which generate digital output signals depending on the position of the operator handle (1). For this purpose, each switch has a maximum of 5 (S41 to S43) or 4 (S44 and S45) micro-switches (2) with varying switching programs, thus providing for adaptability to the customer’s demands. Besides the switching program, the micro-switch type, the electric interface, the colour of the centering rings (4), and the mechanical features (angle of deflection of the operator handle, form of the...

Industrial Controllers Technical Documentation Figure 2 provides information on the lever switch’s basic design features. As one can see, it basically consists of an operator handle (1), which is supported by a flange plate (2). The form of the operator handle can vary. See the dimension drawings of the units (S41 – S45). Below the flange plate, the operator handle is connected with a detent disk (3), which is operated by a spring loaded roller lever (4). This is the operating principle behind the mechanical detent and spring return functions. All of the default detent and spring return functions...

Industrial Controllers Technical Documentation The micro-switches (6) are activated by cam discs (7). Basically, there are two types of microswitches available: 1. Micro-switch without positive opening operation These micro-switches are used in the lever switches S41, S42, and S43. Each lever switch includes a maximum of 5 micro-switches. The technical data of these micro-switches is listed in chapter 4. 2. Micro-switch with positive opening operation These micro-switches are used in the lever switches S44 and S45. Each lever switch includes a maximum of 4 micro-switches. The technical data of...

Industrial Controllers Technical Documentation Lever switch installation With anti-twist device Without anti-twist device Figure 3 shows the installation of the lever switch. As one can see, the lever switch (1) is inserted into the port (2) from below, and the centering ring (3) is placed upon it from the top. Fix the entire unit by tightening the two attachment screws (4) evenly (NOTE: Max. Torque 50 Ncm!!). Make sure to remove the cylindrical handles (handles 13 and 14) before inserting the lever switch into the port. You will find a detailed instruction for the disassembly of the handles...

Industrial Controllers Technical Documentation Handle disassembly The handles 02, 03, 05, 13, 14, and 15 are put over the switching lever and then fixed axially by a hex-socket set screw (M3 DIN 916). Upon the loosening of this set screw, the handles can be removed upwards. For the handles 13 and 14, a cover must be removed first (see fig. 4), before one can access the set screws. When tightening the set screws, make sure not to exceed the max. torque of 20 Ncm. grip cover set screw handle Figure 4: Handle disassembly Type Key contact 2 contact 1 handle design colour of centering ring lock against...
