A103SYCQ04 is a 1 Pole toggle switch from the Gemini Series A, designed for PCB mounting applications with silver (Ag) contact material. The switch features three positions: On-Off-On, providing a center-off configuration suitable for applications requiring momentary or maintained switching with a neutral center position. With silver contacts, this switch offers reliable electrical performance and good conductivity for general-purpose switching applications. The PCB mounting design enables direct integration into circuit boards, making it ideal for consumer electronics, industrial control panels, and instrumentation systems where compact, reliable switching is required.
