Sealed Snap Action Switch
D2SW
Watertight Miniature Snap Action Switch
• High-quality watertight miniature Snap Action switch.
Switch Body meets IP67 (IEC 529) requirements
• Monoblock construction assures high sealing capability and
is ideal for dusty places or where water is sprayed
• Wide operating temperature range of -40°C to 85°C
• Perfect for the automobile, agriculture machinery, automatic
vending machine, refrigerator, ice-manufacturing,
hot-water supply, air conditioner, and industrial equipment,
which require highly environment-resistive capabilities
• RoHS Compliant
