Low assembly height, pleasant feel and excellent contact reliability thanks to GoldCrosspoint contact technology allow flexible designing of low-cost keypads and keyboards. Depending on the key cap, different lead spacings are also possible. Very short bounce times, very pleasant feel and exceptionally high reliability and durability pave the way for a wide range of applications. 2 Materials Insulation materials Spring Contacts Other Characteristics Protection class Operating temperature Storage temperature Humidity (without condensation) Soldering capability Soldering temperature/duration 3 ® Keymodule ML Keycaps and mechanics Description The Cherry ML key module is a mechanical switching element using single-gap make contact element in Gold-Crosspoint contact technology. Its pleasant feel makes the module particularly suitable for low-cost construction of keyboards and keypads with great diversity and very low height. A multitude of different cap shapes allows flexible designs. Very short bounce time, reliable stroke, pleasant feel and enormous cost-savings pave the way for a wide range of applications.
