C&K Develops Sealed Subminiature Snap-acting Switch

C&K ZMW Series


September 16, 2020

C&K has launched a silent, sealed, subminiature, snap-acting switch series that offers precise actuation in automotive applications. The compact ZMW Series snap-acting switch combines a long stroke with more than 2 mm of over travel for reliable actuation. The ZMW Series is used in rugged environments including automotive, industrial, white good and other applications.

The ZMW has a twin sliding contact design that prevents contaminants from entering the switch, which may affect the performance and operating life. The sliding contact design ensure long term reliability and operation up to 500,000 cycles.

Available in pin plunger & lever, and terminals & wire harness versions, the ZMW Series offers design flexibility and makes integration into customer designs simply and easy. Full IP67 protection when potted with wire version and IP67 for standalone switch except the metal terminal part.

The ZMW Series is commonly designed into vehicle door and latch detection applications, industrial pumps, oil & gas pumps, and home appliances like stoves, HVAC and washing machines.

The ZMW Series has an operating temperature of -40°C to 85°C for signal current application.

  • Long and adequate stroke setting for high reliability and insulation
  • Silent for noiseless application
  • Compact size – ideal when space is limited
  • Twin contacts design – sliding contacts prevent pollution of foreign materials
  • IP67 for standalone switch except the metal terminal part; full IP67 protection when potted with wire version
