The 78H01ST is a thru-hole DIP switch featuring 4PST (four pole single throw) circuitry with a single position and raised slide actuation. It measures 0.480 inches (12.2 mm) in length and is designed with spring and ball contact technology, sealed base standard construction, and optional top tape seal for machine soldering applications. The switch operates over a temperature range of -40°C to +85°C with a mechanical life rating of 2,000 operations per switch position, supporting current carry ratings up to 4 A with a maximum 20°C temperature rise. This component is ideal for industrial control panels, instrumentation, and embedded systems requiring reliable manual configuration switching with multiple independent circuits.
