Common Pitfalls When Sourcing Power Switches (Quality, IP Rating)

Sourcing power switches involves more than just finding a component that fits electrically and mechanically. Two critical areas where buyers often encounter issues are quality consistency and misinterpretation or inadequate specification of Ingress Protection (IP) ratings. Overlooking these aspects can lead to product failures, safety hazards, and increased long-term costs.

Poor Quality and Inconsistent Manufacturing

One of the most frequent pitfalls is selecting power switches based solely on cost, often from suppliers with lax quality control. Low-cost switches may use substandard materials—such as brittle plastics, low-grade contacts, or weak springs—that degrade quickly under normal use. This leads to premature failure, inconsistent actuation, or even complete switch malfunction. Additionally, inconsistent manufacturing processes can result in variations between batches, making it difficult to ensure reliable performance across production runs. Without proper certifications (e.g., UL, CE, RoHS) or test reports, it’s challenging to verify reliability, especially in demanding environments.

Misunderstanding or Misapplying IP Ratings

Another major pitfall is assuming that a switch labeled with an IP rating (e.g., IP65, IP67) will perform as expected in real-world conditions. Many buyers overlook how installation affects the final protection level. For example, a switch with an IP67 rating may only achieve that protection when properly mounted with the correct gasket and panel thickness. If the panel is too thin or the cutout is imprecise, water and dust can bypass the seal. Furthermore, some suppliers may exaggerate or misrepresent IP ratings without third-party testing. Always verify test documentation and consider environmental factors like vibration, temperature cycling, and chemical exposure that can degrade sealing over time.
