This microswitch from IMI Norgren does its best work under pressure. It's used to make sure hydraulic fluid doesn't drop beyond fixed limits, helping you maintain stability in the system as a whole. If fluid pressure falls below 11 bar, a soft-seal piston actuator triggers the switch so the low flow can be corrected. When it returns to 17 bar, the switch turns off again. Thanks to a PFTE/NBR O-ring, you can be sure even tough media like oils and petroleum-based liquids can't penetrate the seal, keeping the delicate electronic components safe and dry.
