KWQMY1-0Z Round Hermetically Sealed Micro Switch
SPDT Changeover · Φ11mm Round Body · Welded Metal Shell · GJB 809B-2013
Outline & Dimensions (mm)
1. Product Overview
The KWQMY1-0Z Series is a round-format miniature hermetically sealed micro switch featuring all-welded metal shell construction. With a compact Φ11 mm body diameter, it is designed for space-constrained applications where traditional rectangular switches cannot fit, while maintaining full hermetic integrity and high-reliability industrial-grade qualification.

5. Installation
Leaf spring actuator mechanism. In free state (C-NC closed), actuator lever must not contact switch leaf. Actuator depresses leaf to ≥ 0.6 mm for contact transfer (C-NC open, C-NO closed). Refer to outline drawing for mounting dimensions.
- Disconnect power before installation, removal, wiring, or maintenance.
- Precision device — incorrect force on actuator will cause damage.
- Apply force perpendicular to actuator axis only.
