This document is the STSSS2221 product specifications, which mainly explains the product's appearance, structure, dimensions, electrical performance, etc.
The STSSS2221 is a slide switch intended for low‑current circuits in electronic equipment. The document lists its operating temperature range of –40 °C to +85 °C, storage temperature limits, and the environmental test conditions used for verification, such as humidity, air pressure and temperature extremes.
Electrical specifications include contact resistance, insulation resistance, and voltage‑proof testing. Mechanical data cover appearance, construction dimensions, operating force, static load robustness, vibration, shock, and solderability requirements. The datasheet also defines endurance limits, such as 15,000 cycles of operation without load, and provides handling and storage recommendations.
