Ultraminiature DW33 series

Sealed ultra-miniature snap action suitable for low current applications. IP67 sealing makes the DW33 series desirable for applications where liquid ingress or exposure to other contaminants is a concern. The silent operating mechanism and long stroke make the DW33 extremely popular in the automotive and all appliance sectors.

  • Extremely small ultraminiature switch with IP67 sealing
  • Silent sliding contact mechanism with long stroke
  • Designed for low current applications
  • S.P.S.T. -N.O. or S.P.S.T. -N.C. forms
  • PCB terminals or wire leads (UL or AVSS)
  • Operating temperature range -40 to 85 °C

Note: The IP67 classification applies to pre-wired variants only. Although the actuator is IP67 sealed, variants with exposed terminals are classified IP00.
