Engineering & Manufacturing Depth
In-house tooling, injection molding and CNC machining teams keep mechanical fits and cost under direct control as the manufacturing source.
WDELE — Supplier Profile & Audit Hub
WDELE Precision Metal Switches & Control Components Engineered for Harsh Environments
Zhejiang Wandu Electric Co., Ltd. is an integrated manufacturer of rugged electromechanical control components, with research, tooling, plastic injection, automated assembly and reliability testing under one roof.
The product range covers vandal-resistant metal button switches, sealed LED pilot indicators, emergency stop controls, rotary selectors and industrial buzzers from Ø6 mm to Ø30 mm mounting diameters — engineered for automated machinery, industrial panels and outdoor equipment.
Independent Airtightness Verification
Beyond standard ingress ratings, our sealed switch assemblies undergo dedicated negative-pressure airtightness inspection to verify internal diaphragm integrity against persistent vapor condensation.

Why Technical Buyers Specify WDELE
Assurance built on engineering depth, consistency, capacity and support.
02
Quality Assurance
Batch-to-Batch Consistency
Standardized SOPs and controlled routing keep contact resistance, actuation travel and finish consistent across production lots and repeat orders.
03
Fulfillment Resilience
Supply Continuity & Price Stability
Automated assembly capacity and direct raw-material relationships keep lead times flexible and pricing steady through demand peaks.
04
Engineering Support
Application Engineering Support
Engineers with electrical and mechanical backgrounds answer panel cut-out, wiring and feasibility questions with clear drawings and documentation.
Process Transparency
Integrated Manufacturing & Assembly Flow
Critical switch-production phases run and can be reviewed under our own roof.
Process 01
Precision CNC Machining
High-speed turning and multi-axis machining produce stainless-steel, brass and aluminum bezels and housings with controlled tolerances.
Process 02
Component Molding
Flame-retardant PA66 switch bases and polycarbonate lens parts are formed on our injection molding lines.
Process 03
Automated Workshop
Automated stamping and component-insertion stations deliver consistent contact and actuation sub-assemblies.
Process 04
Final Assembly
Fixture-assisted assembly integrates multi-contact blocks and custom wiring leads with in-process checks.
Process 05
Reliability & In-line Testing
The in-house laboratory covers airtightness, contact resistance, electrical endurance and environmental checks on production samples.
Process 06
Batch Storage & Dispatch
Semi-finished modules are batch-tagged and protected in storage, so configured orders can be staged and dispatched in traceable lots.
Verification Protocol
Laboratory Testing & Quality Control
Validation methods that back reliability expectations for industrial switch applications.
Airtightness Sealing Test
Simple bubble tests only expose macro voids. Our fixtures apply negative pressure to check internal actuator and diaphragm sealing against creeping vapor intrusion.
Electrical & Contact Integrity
In-line and sample checks cover contact resistance, insulation behavior and dielectric performance that protect downstream PLC and controller input circuits.
Mechanical Endurance & Corrosion
High-cycle actuation rigs simulate prolonged operation, while salt-mist chambers check plating adhesion and corrosion resistance of metal bezels.
