TUNING MAP
Tuning changes how a mechanism behaves. It can alter resistance, positioning, click structure, glide, sound and re-capture without changing the product's basic form.
→
The system that generates resistance, positioning or tactile events.
→
Magnets, springs, tracks, contact surfaces, damping and preload.
→
Snap, click, glide, crunch, sound and transition behavior.
01
What Does “Tuning” Mean?
Slider tuning is the adjustment or selection of variables that influence resistance, positioning, tactile feedback, sound and movement behavior.
A slider can keep the same form, architecture and mechanism while still behaving very differently after changes to magnet layout, spring preload, track geometry, contact surfaces or damping.
Tuning is therefore best understood as configuration, not as a replacement for mechanism classification.

CORE IDEA
Tuning does not change what a product fundamentally is; it changes how that system behaves.
02
Magnetic Tuning
Magnetic tuning changes how attraction, repulsion and spacing shape resistance, snap, positioning and transition behavior.

SPACING / AIR GAP
SNSNSN
SCHEMATIC / NOT TO SCALE
Magnet Count
Changes how many magnetic interactions can contribute across the movement path.
Magnet Size
Physical dimensions influence the magnetic system but do not determine final feel by themselves.
Grade / Strength
Magnet specification can alter pull and snap, but geometry and distance still matter.
Polarity
Attraction and repulsion patterns shape positioning and transition behavior.
Spacing
Distance between magnets changes how force rises and falls through the movement.
Layout
Linear, paired, inner/outer or other arrangements can produce different response patterns.
NOT A QUALITY SCALE
Stronger magnets do not automatically create a better slider.
A stronger magnetic system can increase pull, resistance or snap, but whether that is desirable depends on geometry, mass, contact surface, movement style and intended tuning.
03
Mechanical Tuning
In spring-and-contact systems, tactile feedback emerges from the relationship between spring force, contact element and track geometry.
SPRING
BALL / BEAD
TRACK
Spring Force
Changes how strongly the contact element is pushed into the track.
Preload
Sets the starting compression or contact force before movement begins.
Ball / Bead Size
Changes contact geometry and how the element enters and exits track features.
Ball Material
Can affect wear, sound and surface interaction depending on the mating track material.
Track Geometry
Depth, slope, spacing and profile influence how each tactile event develops.
Track Density
Closer repeated features can create more frequent tactile events across the stroke.
TERMINOLOGY NOTE
A detent describes a positioning or feedback behavior/system. The actual components may include a spring, ball, bead, groove, track or other contact geometry.
04
Contact Surfaces & Wear Plates
Changing only the working interface can noticeably alter glide, drag, noise and wear even when the body material and mechanism stay the same.
Metal-on-Metal
Two structural surfaces contact each other directly during movement.

Feedback Configuration
Click count describes distinct tactile positions or events. It does not identify architecture or mechanism.
Two distinct tactile events
Used when the movement cycle is dominated by two clear positions or feedback points.
Three distinct tactile events
Describes a three-position or three-event feedback configuration.
Repeated discrete feedback
More than a small two- or three-event configuration across the usable movement.
No small set of dominant clicks
Feedback may vary continuously rather than resolving into a few fixed positions.
CLASSIFICATION RULE
2-Click / 3-Click = Feedback Configuration
Not architecture. Not mechanism. Not material.

Feel & Feedback Character
Feel words are useful for describing experience, but many enthusiast terms are subjective and should not be presented as standardized engineering measurements.

DENSE / SUPER-DENSE
Useful community language, not a standardized technical unit.
“Dense” and “super-dense” are commonly used to describe closely spaced or highly frequent tactile feedback, but there is no universal engineering threshold that defines the terms.

Sound & Acoustics
Tactile feedback and acoustic feedback are related but separate. A strong tactile event does not automatically mean a loud slider.

Why Small Changes Matter
Small hardware changes can alter the force curve, contact event and final sensory result even when the slider still belongs to the same technical categories.
Magnet spacing, spring preload, track depth, liner thickness or another variable changes.
↓
Resistance rises, falls or transitions differently through the movement.
↓
The timing and intensity of snap, detent or surface contact shifts.
↓
The user experiences a noticeably different slider without changing its basic form.
SAME BODY · SAME MECHANISM
Different magnet spacing

Different snap & transition
SAME SPRING SYSTEM
Different track depth

How to Describe a Slider Correctly
Use separate fields for separate technical facts. One marketing phrase should not replace the full product description.

DO NOT OVER-INFER
“3-click magnetic infinite slider”
A phrase like this may contain several clues, but it does not automatically prove the product's architecture, internal layout, play style or exact tuning.
