The 3SE5 position switches differ from the previous series through the following new characteristics:

• The modular structure of the product range allows a number of versions with a smaller number of bearing types for enclosures and operating mechanisms.
• All operating mechanisms can be rotated around the axis in increments of 22.5°.
• Rounded and roller plungers according to EN 50041 with 3 mm overtravel (total travel 9 mm) for greater tolerance when switching.
• All enclosure sizes – now also including the small enclosure 31 mm wide – are optionally available with an LED signaling indicator.
• All enclosure variants have an integrated chlorinated rubber diaphragm for high functional safety in cold and aggressive environments.
• All contact blocks are replaceable, see "Accessories and spare parts".
• The three-pole contact blocks are available for all enclosure sizes.
• Elements with 1 NO + 2 NC slow-action contacts with make-before-break and 2 NO + 1 NC
• The short-stroke contact block 1 NO + 1 NC improves the precision of the switching operation through a reduced actuation path.
• The contact block with 1 NO + 1 NC snap-action contacts with 2 x 2 mm contact opening is suitable for simultaneous shutdown and signaling, particularly in the elevator industry.
• XL metal enclosures for accommodating two 2- or 3-pole contact blocks
• The plastic enclosures with a width of 31 mm have simple and fast wiring equipment, making it possible to achieve time savings of approx. 20 to 25 % when connecting (see figure for quick-connect technology).
