Editing ITW magnetic valve (section)

===Low-profile===
The most common variant of this switch is the low-profile version with an open shell. The switch should not be be confused with the [[RAFI RS 76 C]] Hall effect switch, with which it bears more than a passing resemblance, in particular the open low-profile shell, slider, and keycap mount.

The low-profile version has no spring under the slider; consequently, a [[buckling rubber sleeve]] is placed within the keycap to act as the return spring. These switches are tactile, with around 60 cN force.<ref name="gh-KMX-144" />

The switch contains a circular recess for an LED.<ref name="DT-LED" />

Comparing the switches in the Devlin KMX-144 and Decision Data keyboards, it's clear that at least two subtle variations of this switch were made, evident by examining the LED recess.
