ASCO SA11A TriPoint Pressure Switch

The ASCO SA11A TriPoint Pressure Switch is a SA-series switch unit designed to be paired with a transducer to form ASCO’s TriPoint pressure/temperature switching assembly, catalogued as SA11A. It delivers robust electrical switching across a range of AC and DC supplies with a resistive switching capacity of 5 A at 125 or 250 VAC; 1/2 A at 125 VAC, 125 VDC; 1/4 A at 250 VAC, 125 VDC; and switching power up to 90 W at 125 VAC or 180 W at 250 VAC, making it suitable for energizing relays, solenoids, or control circuits directly from a monitored pressure signal. The unit is rated for ambient temperatures up to 60 C, enabling operation in typical industrial environments where space and mounting considerations matter. The SA11A is part of ASCO’s SA-series of switch units, designed to be used with transducer units to create Tripoint switches, providing a compact, modular solution for integrating pressure sensing with conventional electrical control systems. With its catalog number SA11A and the ability to operate across multiple voltage levels, the SA11A offers a flexible option for designers and maintenance engineers seeking a dependable, field-serviceable pressure switch component that can be wired into standard AC or DC control circuits without requiring extensive enclosure or wiring changes.
