Executive Summary

Sourcing DPDT (Double Pole Double Throw) switches from China offers competitive pricing, scalable production, and access to a mature electronics supply chain. However, procurement risks—including misrepresentation of supplier type, quality inconsistencies, and supply chain opacity—remain prevalent. This report outlines critical verification steps to identify genuine manufacturers versus trading companies, highlights red flags, and provides actionable due diligence protocols for global procurement professionals.

---

Critical Steps to Verify a DPDT Switch Manufacturer in China

Step	Action	Purpose
1	Request Business License & Scope of Operations	Verify legal entity status and confirm manufacturing is listed in the business scope (e.g., “production of electrical switches”).
2	Conduct On-Site or Third-Party Factory Audit	Physically inspect production lines, machinery (e.g., stamping, molding, assembly), and quality control labs. Use SourcifyChina’s audit checklist.
3	Review Equipment List & Production Capacity	Confirm ownership of key machinery (e.g., CNC presses, automated testers). Factories own equipment; traders do not.
4	Evaluate R&D and Engineering Capabilities	Assess in-house design teams, mold-making facilities, and ability to customize switch specs (e.g., contact resistance, actuation force).
5	Request Sample Traceability & Batch Records	Require proof that samples originate from the supplier’s production line (with batch numbers, test logs, and QC stamps).
6	Verify Export History & Client References	Request 3–5 verifiable export clients (preferably in EU/US) and contact them for performance feedback.
7	Check Certifications	Confirm valid ISO 9001, IATF 16949 (for automotive), UL, CE, RoHS, and CCC (if applicable). Certificates must be issued to the manufacturer, not a trading name.

---

How to Distinguish Between a Factory and a Trading Company

Indicator	Genuine Factory	Trading Company
Business License	Lists “manufacturing” or “production” in scope	Lists only “import/export” or “trading”
Facility Ownership	Owns factory premises or long-term lease	No production space; operates from office only
Equipment	Possesses injection molding machines, stamping presses, automated testers	No production equipment on-site
Mold Ownership	Owns custom molds for switch components	Relies on third-party mold owners
Lead Time Control	Direct control over production scheduling	Dependent on factory lead times; less flexibility
Pricing Structure	Provides cost breakdown (material, labor, overhead)	Offers fixed FOB pricing with limited transparency
R&D Team	Has in-house engineers for design and testing	No engineering staff; relays requests to OEMs

Pro Tip: Factories typically have lower MOQs for custom designs and faster iteration cycles. Traders often impose higher MOQs due to third-party dependencies.

---

Red Flags to Avoid When Sourcing DPDT Switches

Red Flag	Risk Implication	Recommended Action
No verifiable factory address or Google Street View mismatch	Likely a front office or shell company	Conduct on-site audit via third party (e.g., SGS, SourcifyChina)
Reluctance to share production videos or live factory tour	Hides operational deficiencies	Require real-time video walkthrough of assembly and QC lines
Samples shipped from different city than claimed factory	Sourcing from multiple unvetted suppliers	Verify sample origin via logistics documentation
Unrealistically low pricing (e.g., 40% below market)	Indicates substandard materials (e.g., brass instead of silver alloy contacts)	Conduct material composition testing (XRF analysis)
No direct communication with engineering or production staff	Lack of technical control	Request direct contact with plant manager or QC lead
Pressure for full prepayment or lack of secure payment terms	High fraud risk	Use LC, Escrow, or milestone-based payments (30% deposit, 70% post-inspection)
Generic product photos or stock images	No real production capability	Require time-stamped photos of actual production runs

---

Best Practices for Risk Mitigation

1. Use Escrow or LC Payments: Avoid full upfront payments. Use 30–50% deposit with balance after third-party inspection.
2. Enforce IP Protection: Sign NNN (Non-Use, Non-Disclosure, Non-Circumvention) agreements before sharing designs.
3. Implement AQL 2.5 Inspections: Conduct pre-shipment inspections via independent agencies.
4. Require Long-Term Capacity Commitment: Secure production slots for 6–12 months to avoid allocation risks.
5. Leverage SourcifyChina’s Verified Supplier Network: Access pre-audited DPDT switch manufacturers with compliance documentation.

---
