Robust metal pushbutton switch family with 16 A switching current at 250 VAC

SCHURTER's MSM LA and MSM LA CS latching-action stainless steel and ceramic surface pushbutton switches are available with a maximum rated switching current of 16 A at 250 VAC, uprated from 12 A. Designed for primary ON/OFF switching, the up-rating on the MSM LA and LA CS expands on their suitability for use in appliances with higher loads.     

SCHURTER's MSM LA series offers a classic stainless steel actuator, with optional point or ring illumination, while the MSM LA CS series offers SCHURTER's innovative scratch resistant backlit ceramic surface. The LED supply voltage is 24 VDC. The multi-faceted pushbuttons are available with mounting diameters of 19 and 22 mm, and equipped with blade terminals for quickly affixing wires: the pre-assembled cable set is plugged into the quick-connect terminals of the microswitch, which is then snapped into the switch housing. The MSM LA and MSM LA CS series switches comply with the EU low voltage directive, IEC 61058-1 and UL 1054 standards. The microswitches are ENEC, UL, CSA and
CQC approved.
