Overview
IEC 61058-2-4:2018 - “Switches for appliances - Part 2‑4: Particular requirements for independently mounted switches” specifies safety and performance requirements for independently mounted mechanical or electronic switches used to operate or control household and similar appliances. It covers switches actuated by hand, foot or other human activity, with a rated voltage not exceeding 480 V and a rated current not exceeding 63 A. This 2nd edition (2018) replaces the 1995 edition, aligns the format with the IEC 61058 series structure, and incorporates Annexes K and M as normative (Annex L informative). It is intended to be used together with IEC 61058‑1:2016.
Key topics and technical requirements
The standard supplements and modifies the general requirements in IEC 61058‑1 and focuses on aspects specific to independently mounted switches:
- Scope & definitions: clarifies “independently mounted switch” and design types (Design A and B).
- Ratings and classification: rated voltage/current limits and classification by degree of protection and intended use.
- Marking and documentation: required product information, identification and instructions.
- Safety protections: requirements for protection against electric shock, earthing provisions and terminals/terminations.
- Construction & mechanism: mechanical design, actuator arrangements, and internal construction for safe operation.
- Environmental protection: ingress protection, resistance to humidity, dust and water where applicable.
- Electrical tests: insulation resistance, dielectric strength, clearances and creepage distances.
- Reliability tests: heating, endurance, mechanical strength, resistance to rusting and abnormal/fault condition tests.
- Fire and tracking resistance: requirements for materials and coatings to limit fire hazard and tracking.
- EMC and components: electromagnetic compatibility requirements and rules for substituted components.
- Annexes: routine tests (K), sampling tests (L - informative), and switch family provisions (M).
Applications
IEC 61058‑2‑4 is directly applicable to:
- Manufacturers of independently mounted switches for household and similar appliances.
- Design engineers specifying switch components or actuator interfaces.
- Test laboratories and certification bodies performing conformity assessment and type testing.
- OEMs integrating switches into appliances or remote-actuated controls.
- Regulatory and compliance teams ensuring product safety for markets using IEC standards.
Who should use this standard
- Switch designers and component manufacturers
- Appliance manufacturers and product development teams
- Compliance engineers, safety assessors and test houses
- Certification bodies that assess electrical safety of appliance controls
