Plastic mechanisms and housings are acetal to minimize moisture absorption and maintain dimensional stability. Plastic welding is accomplished using advanced microprocessor controlled ultrasonic welding equipment. All switches are 100% tested at high and low settings and at the proof pressure. Units are delivered with the setpoint at the low end of the adjustable range. The pressure switches and vacuum switches are field adjustable using the hex head set screw at the center of the pressure switch.
