Rotary wafer switches (low current rating). Part 3 : Rotary wafer switches with two-hole mounting

This technical specification addresses the specific requirements for blade switches operating under small current ratings, focusing exclusively on versions designed for dual-hole mounting configurations. It establishes precise criteria concerning dimensions, material specifications, electrical endurance, and mechanical durability to ensure reliable performance across diverse applications. The document outlines testing procedures intended to verify that the switches meet defined operational limits when subjected to repeated actuation cycles under nominal load conditions. Emphasis is placed on the structural integrity of mounting interfaces, ensuring compatibility with standard enclosure layouts while maintaining safety margins during electrical switching operations. By defining uniform parameters for contact resistance, dielectric strength, and environmental resistance, this document facilitates global interchangeability of components in low-voltage control circuits. The content serves as a reference for manufacturers developing compatible switching devices and for testers evaluating conformity against established benchmarks. All provisions aim to harmonize product characteristics without altering fundamental operational principles inherent to this switch category.
