Inquiry (采购产品): barometric pressure switch Hi, We are looking to redesign an altimeter warning system for a very old military aircraft. The old barometric switch is an obsolete part from Edcliff Instruments (121632), a company no longer in existence. The requirements for the switch are as follows: 1. Switch closes at an altitude of 700+/- 200 feet above a setable reference altitude during ascent. 2. Switch remains closed to limit of 30K ft. 3. Switch opens at an altitude of 700+/- 200 feet above the reference altitude during descent. 4. Reference altitude can be set anywhere from sea level to 6000 ft. 5. 27.5 V dc nominal (25-29V limits) 6. -25 to + 55 degrees C operational temp Is there anything in your product line that we might look at?
