Compared to other switches in the field, a new series is designed to be slightly larger in diameter and to use a conventional snap-action switch as its main switching element. This is said to be an indication of its reliability and dependability. The new line is available in pressure, vacuum or differential models with standard multi-barb port connections, orifices, bleed holes, and various mounting configurations. The switches are factory calibrated to specific customer requirements from 0.1 inch H20 to 5.0 inch H20. The piggy-back design allows the use of different snap-acting switches. The company also has the ability to offer different size electrical terminations within the same unit, which is said to be a valuable safety feature that prevents field technicians from incorrectly wiring the switch during routine service calls.
