HP-3 Extended Duty Pressure Switch

The extended duty pressure switch is specifically designed to stand up to extended duty applications. This switch is factory set but capable of field adjustment. The extended duty pressure switch features different diaphragms for compatibility with a wide variety of fluids, and various terminations including a Metric-Pack connector that forms a tight seal when connected. Among the outstanding design benefits are its durable construction, compact size, and enhanced set point integrity. It can be widely used for pool and spa, anti-skid braking systems, water pump systems, dental air compressors, etc.
