C&K Introduces DS Series of Door Interlock Switches

In some applications, it is necessary to have a power shut down when a panel door is open for service to avoid any incident. The same kind of switch can also be used for a signal indication against tampering.

C&K’s DS series door interlock provides design flexibility by offering over-travel options ranging from 3.2 to 13.2mm to address your most difficult hardware tolerance stack up. The DS is available in single and double pole models, latching and momentary functions, and snap-in mounting or quick connect terminals for easy installation.

This switch is offered in 3 actuator styles: short (11.45mm), long (22.25mm) or push/pull or “cheat” to better fit inside the final application.


  • Silver and gold plated options for logic level and power circuits (up to 16A)
  • 10 000 to 100 000 life cycles
  • UL61058-1 approved with ENEC for international use
