Abstract
A rotary switch or controller is structured to have a so-called impact criteria or characteristic by having members with predetermined yield, or breaking, points (5, 6) which are integrated into the rotary switch (1) so that when a high force acts on the rotary switch (1), a top part (2) of a rotary switch or rotary controller (1) is allowed to be collapsed into a front panel (4) of a passenger vehicle or commercial vehicle on which the rotary switch is used. These yield elements (5, 6) may be structured as ribs (6) that have intended breaking points (6.1) therebetween, or may be structured as spring elements (5).
Claims15
A rotary switch having a rotary knob and a rotary-knob lower part formed as a separate piece from said rotary knob but cooperating therewith to transmit switch adjustments, wherein the rotary switch has members with predetermined yield points located on an outer perimeter of one of the rotary knob and the rotary-knob lower part for supporting the rotary knob, so that when a high force acts on the rotary switch, the members with predetermined yield points yield at these yield points and the rotary knob is collapsed toward the rotary-knob lower part, wherein the members with the predetermined yield points are formed as pieces separate from said rotary knob and the rotary-knob lower part;
- and
- wherein there is a key element that is additionally integrated into the rotary knob top part, and a holder that mechanically holds the key element, with the rotary-knob lower part being positioned on the holder, wherein said holder has retaining fingers engaging in guide grooves in the periphery of the key element.
A rotary switch having a rotary knob and a rotary-knob lower part formed as a separate piece from said rotary knob but cooperating therewith to transmit switch adjustments,
- wherein the rotary switch has members with predetermined yield points located on an outer perimeter of one of the rotary knob and the rotary-knob lower part for supporting the rotary knob, so that when a high force acts on the rotary switch, the members with predetermined yield points yield at these yield points and the rotary knob is collapsed toward the rotary-knob lower part,
- wherein the members with predetermined yield points are formed of pieces separate from said rotary knob and the rotary-knob lower part and they are located in recesses of the one of the rotary knob and the rotary-knob lower part before the rotary knob is collapsed toward the rotary-knob lower part.
A rotary switch having a rotary knob and a rotary-knob lower part formed as a separate piece from said rotary knob but cooperating therewith to transmit switch adjustments,
