Product Specifications

Technical details and manufacturing context for Switches

Definition

Switches in the output stage/charge pump are electronic components that selectively open or close electrical circuits to control the charging and discharging cycles, regulate voltage conversion, and manage power distribution within the system. These switches are typically semiconductor-based (e.g., silicon) or electromechanical, with contacts made of copper alloy or silver tin oxide (AgSnO2) for high arc resistance. They are mounted on ceramic substrates for thermal and electrical insulation. The switches operate by changing their state between conductive (closed) and non-conductive (open) positions, controlled by external signals such as voltage, current, or digital commands, to direct current flow through specific paths in the charge pump circuit for voltage multiplication or regulation. Key parameters include rated voltage up to 250 V AC, rated current up to 10 A, contact resistance ≤50 mΩ (initial, after life test ≤100 mΩ), insulation resistance ≥100 MΩ at 500 V DC, dielectric strength of 1500 V AC for 1 minute, operating temperature range -25 to 85 °C (storage -40 to 85 °C), mechanical life of 100,000 cycles (no load), electrical life of 50,000 cycles (at rated load), ingress protection IP54 to IP65, actuation force 2-5 N for toggle switches, and weight 10-20 g depending on configuration. Housing material is PA66 with V-0 flame retardancy. These switches are used in power management applications, such as charge pumps for voltage conversion. This directory entry references IEC 60669, IEC 60512-2, IEC 60068-2-1, IEC 60068-2-2, and IEC 60529 for procurement verification. IEC 60068-2-1 and IEC 60068-2-2 are cold and dry-heat test methods and do not establish the listed temperature ranges; testing and compliance must be confirmed for the specific switch. It is essential to verify model-specific values and standards with the legal manufacturer or supplier before procurement or integration.

Working Principle

Switches operate by changing their state between conductive (closed) and non-conductive (open) positions, typically controlled by external signals (voltage, current, or digital commands) to direct current flow through specific paths in the charge pump circuit for voltage multiplication or regulation. In a charge pump, switches are used to alternately connect capacitors to the input and output, enabling energy transfer and voltage conversion. The switching action is synchronized to control charging and discharging cycles, ensuring efficient power distribution. The state change is achieved through semiconductor junctions or mechanical contacts, depending on the switch type. The control signal determines the switch state, allowing precise regulation of the output voltage.

Frequently Asked Questions

What are the typical voltage and current ratings for these switches?

According to the directory data, the rated voltage is up to 250 V AC and rated current up to 10 A, per IEC 60669. However, actual ratings may vary by model, so always confirm with the manufacturer.

What is the contact resistance specification?

The initial contact resistance is ≤50 mΩ, and after life test it should be ≤100 mΩ, as per IEC 60512-2. This ensures reliable electrical performance.

What environmental protection do these switches offer?

The ingress protection rating is IP54 to IP65, meaning they are protected against dust and water. This is per IEC 60529. Verify the exact rating for your specific model.

What standards are relevant for these switches?

Relevant standards include IEC 60669 for switches, IEC 60512-2 for contact resistance, IEC 60068-2-1/2 for temperature, and IEC 60529 for ingress protection. Always check compliance with the manufacturer.
