anyone know the way of this test for
it is a pressure switch to monitor the hydraulic pressure. (like your home well water pump switch.) It is just a pair of on-off contacts. In old days, +28 VDC in, thru the switch out to the lamp, then go back to -28 VDC. (nowadays, maybe lower voltage and mA current to PC.)
How to test this PRESSURE SWITCH per RTCA/160D, section 22, waveform 3, table 22-3 cable bundle, level 4, 1500 V and 300A?
Thanks
