Miniature Door Switch

D3D

Unique Mechanism Allows Switching of

Micro Loads

• Choose from plunger or lever actuators.

• The internal structure of plunger models provides

temporary sealing at the free position.

• Low operating force of 204 g max.

• Disconnectable crimp connector for easier wiring.

• High contact reliability ensured with gold crossbar contacts.

• Low noise operation.

• RoHS Compliant.
