There are various cheaper alternatives on the market, though typically from less well-known brands. The balance between cost and reliability is a key consideration.
Frequently Asked Questions (FAQs):
- •Q: What is a DPST pressure switch? A: DPST stands for Double-Pole, Double-Throw. This means the switch controls two circuits simultaneously, providing more versatile control options for the air compressor system.
- •Q: Can this pressure switch be adjusted? A: No, this particular model has a fixed pressure setting of 50/70 psi. If you require adjustable pressure settings, you'll need to look at other models.
- •Q: How does the diaphragm mechanism work? A: The diaphragm is a flexible membrane that senses changes in pressure. When the pressure reaches the cut-in point, the diaphragm activates the switch, and vice versa for the cut-out point.
Comparison with Competitors:
While Square D maintains a strong reputation for quality, it's worth comparing this pressure switch to competitors like Gast and SMC. Gast offers a range of pressure switches at various price points, while SMC often focuses on higher-precision applications. A direct comparison requires analyzing specific model specifications and user reviews to determine which best suits individual needs.
