This document is a specification for a low current circuit (secondary circuit) push switch used for electronic equipment. It specifies the application, operating temperature range, appearance, construction and dimensions, rated voltage and current, electrical performance, etc. of the push switch.
This document specifies the performance and test criteria for the Alps STSPPHI11 switch. It includes electrical parameters such as contact resistance, insulation voltage and voltage proof tests, as well as mechanical requirements like operating force and durability.
The specification also defines environmental tests, including cold, dry heat, damp heat, and salt‑spray exposure, and provides solderability and PCB thickness requirements. The switch is rated for 10,000 operating cycles under defined load conditions.
