Microminiature Slide Switches

Product catalog summary

Specifications Overview:
Microminiature slide switches are designed with various specifications to suit different applications. The contact rating varies between 12 V DC, 200 mA and 24 V AC/DC, 0.3A, with contact resistance ranging from less than 30 mΩ to 70 mΩ. Insulation resistance is consistently above 100 MΩ at 500 V DC, ensuring high reliability. The dielectric strength is maintained at 500 V, 50 Hz for one minute across all models. Operating temperatures range from –40° to +85° C, with mechanical life spanning a minimum of 5,000 to 10,000 operations.

Materials and Construction:
Contacts are typically made from phosphor bronze or brass, with silver or gold plating to enhance conductivity and durability. Terminals are also brass, silver, or gold-plated. The switches feature non-shorting contact timing and are available in various slide colors, primarily white, with some models in black.

Soldering Conditions:
Soldering conditions vary by model, with auto-soldering temperatures reaching up to 270º C for a maximum of 5 seconds, and reflow-soldering conditions allowing up to 60 seconds at 260º C. These conditions ensure the switches can be securely mounted onto circuit boards without damage.

Model Variations:
The document lists several models with different switching functions, such as MMP 121, MMP 131, and MMSP 132, each offering unique configurations like 'on-on' or 'on-on-on'. Some models include additional features like pushbutton functions.

Packing and Storage:
Switches are packed in reels or cardboard boxes, with quantities ranging from 900 to 1000 pieces per reel. Storage temperatures are specified for some models, extending from –20° to +70° C, ensuring product integrity during storage and transport.
