Grayhill 78HF01GWT SPDT Slide DIP Switch
The Grayhill 78HF01GWT is a surface mount dual-pole, single-throw (SPDT) DIP switch designed for integration into a wide range of electronic devices. Its slide actuator provides tactile feedback, while the robust construction ensures reliable performance in demanding environments. Compatible with infrared reflow and vapor-phase SMT assembly, this switch simplifies manufacturing processes. The gold-plated over nickel barrier on the shorting member and base contacts enhances conductivity and corrosion resistance, making it suitable for applications requiring high reliability and longevity. Typical applications include industrial control panels, consumer electronics, and automated equipment.
