(See Fig 3) <br />The witch unit shall contain SPDT(Form C) switch(es) One switch shall be <br />set to operate at a pressure decrease of 10 PSI (0,7 BAR) from named If two <br />switches are provided, the second switch shall be set to operate at a pressure <br />increase of 10 PSI (0,7 BAR) fiom normal. <br />Switch contacts shall be rated at 10. I Amps at 125250VAC and 2.0 Amps at <br />30VDC. The units shall have a maximum pressure rating of 300 PSI (20.68 BAR) <br />and shall be adjustable from 10 to 60 PSI (0,7 to 4,1 BAR). <br />Pressure switches shall have hw1 conduit entrances, one for each individual switch <br />compartment to facilaftle the use of dissimilar voltages for each individual switch <br />The rover of the pressure switch shall be 7" die-cast with rain lip and shall attach <br />With one tamper resistant xrsv.
