DS0001

C&K DS series snap-action interlock switch

The read
Littelfuse ended China production of the C&K DS snap-action line on July 31, 2026, and Morocco production does not ship until December 2026. That leaves a four-month supply hole that is open right now, not at some future LTB date. These interlock switches sit in safety circuits in medical and industrial equipment, where substitution means requalification.
