The 78B10SRAT is a 10-position right-angle DIP switch manufactured by Grayhill, featuring SPST (Single Pole Single Throw) circuitry with easy access and sealed tape option. It offers mechanical life of 2,000 operations per switch and electrical life of 10,000 operations at 24VDC, 25mA, with a switching rating of 150mA at 30VDC and non-switching rating of 100mA at 50VDC. The switch operates reliably across a temperature range of -40°C to +85°C and features low contact resistance of 30mO maximum at initial contact, with insulation resistance of 5,000MO minimum at 100VDC. Materials include brass contacts with gold plating over nickel, plastic nonconductive parts (UL94V-0), and epoxy potting, making it suitable for telecommunications, computers, peripherals, instruments, and control applications where compact right-angle mounting and sealed reliability are required.
