– suitable for switching low-level electronic currents  
Double-break contacts with electrically separate NO and  
NC circuits in conformity with VDE 0660 part 206  
10A 500VAC/600VDC rated  
Lever types can be user-set to switch by clockwise  
movement only, anti-clockwise only or both  
Turret head position rotatable in 90˚ increments  
Centre-position indicator arrow – lever actuators  
Wide range of actuators  
Single and triple cable entry models  
Removable contact block for ease of wiring

Note: The positive break of the type 5 contact block applies to the NC contacts  
only. Connections to safety circuits should NOT be made using the NO  
contacts.  
To ensure positive breaking of the contacts, exceed the pre-travel by 1.5mm or  
25˚ according to the model.

FD/ FP/ FL  
Programmable head – lever operation models  
All limit switches with lever operation in the FD/ FP/ FL ranges can be user-set to switch by clockwise rotation only, anti-  
clockwise only or both. To change the operation, which is factory set to switch in both directions, the four screws securing  
the turret head should be loosened, the head removed and the internal piston rotated through 90˚. The head should then be  
replaced.  
The models to which this applies are: 531; 532; 533; 535; 536; 538; 551; 552; 553.  
Figure 1 shows the piston position for switching in both directions, figure 2 for clockwise only and figure 3 for anti-  
clockwise only.
