DAC Worldwide's Pressure Control Switch Sample Dissectible (272-980) is a realistic dissectible sample of a common industrial control-type pressure switch as used in automation and process systems.  A specialized base and stanchion mounting assembly positions the sample for convenient static viewing or closer inspection by hand after removal from the base assembly. A modular base assembly allows for convenient mounting on optional display, storage, and viewing products. The complete working mechanism including bellows, contact blocks, pressure and differential pressure adjustment mechanisms, trip mechanisms, and connection points can be clearly seen.
