Rotary Switches

Rotary switches – multi-step switching with detent positions for the tail lift

Rotary switches handle the function selection on control panels of tail lifts via a mechanically guided turning movement with defined detent positions. Every step is clearly coded and switches a dedicated circuit, for instance for the modes raise, lower or travel. At SULEJ Ladebordwand you will find rotary switches as replacement parts for worn or damaged control elements on common control boxes of tail lifts and truck lift gates – a central component for the reliable function selection in daily operation.

Rotary switch: multi-step switching with detent positions

Typical of the rotary switch is the switching mechanism with several fixed positions which are mechanically locked by a tangible detent. A common position symbology follows the scheme 0 / I / II / III, each representing one operating mode or function. The internal coding ensures that only the contact assigned to the position is closed, so that misoperation through the position itself is excluded. Housings made of robust plastic, sealed shaft bearings and common IP protection classes for commercial vehicle control elements protect the rotary switch against moisture, dust and cleaning water at the rear portal.

Selection and replacement of a matching rotary switch

When replacing a rotary switch the number of positions, the panel bore dimension, the shaft length and the connection layout are decisive. The position symbology must match the function of the control system, so that the labelling on the control panel remains valid. Before removal it is worth photographing the contact assignment. Replacing a defective rotary switch – recognisable by an unclear detent, a jammed mechanism or a missing operating mode – restores the defined multi-step switching and preserves the operating logic of the tail lift.

Benefits at a glance

• Clear function selection through firmly defined detent positions
• Mechanical coding prevents misoperation between the steps
• Position symbology 0 / I / II / III for clear mode assignment on the control panel
• Robust design for the typical weather and cleaning load on the rear portal

A matching rotary switch secures the reliable function selection and keeps the control panel of the tail lift ready for use even after a long service life.
