Grayhill 78 series DIP switches have SPST, 2PST, 3PST, 4PST and other circuits. The switch length and tube diameter can be selected. The sealed base is standard. It has spring and ball contacts. A top seal is optional.
The Grayhill Series 78 slide switches are offered in single‑pole/single‑throw (SPST) up to four‑pole/single‑throw (4PST) configurations. They are available with raised or recessed slides, sealed bases, spring or ball contacts, and an optional top‑tape seal for solder‑heavy applications.
The sheet provides detailed dimensions for each slide length, circuitry ordering tables, and part‑number conventions. Ordering a top‑seal version requires adding an "S" before the "T" in the Grayhill part number. Distributors can supply the switches worldwide.
