GRAYHILL 78B04ST DIP Sealed Slide Switch, 4 Way

The GRAYHILL 78B04ST is a robust 4-way DIP sealed slide switch, engineered for reliable operation in demanding electronic environments. Featuring a single-pole, single-throw (SPST) contact configuration across four independent circuits, this through-hole mounted component is an essential choice for setting configurations, mode selection, and circuit enabling/disabling on printed circuit boards.

Its standout feature is the sealed switch base, which provides excellent protection against dust, flux, and other contaminants during the PCB assembly and cleaning processes. The raised slide actuator offers a positive tactile feel and is easy to operate, even in densely populated boards.

Built for industrial applications, the switch boasts a wide operating temperature range from -40°C to +85°C, ensuring consistent performance in both frigid and elevated ambient conditions. With a maximum DC contact rating of 30V and 150mA, it is perfectly suited for low-voltage digital logic and signal routing tasks where reliability is critical.

The compact through-hole design facilitates secure soldering and strong mechanical bonds to the PCB. As part of the reputable GRAYHILL 78B series, this switch represents a trusted solution for designers and engineers seeking durable, sealed switching hardware for prototypes, test equipment, and final production units.
