RT Pressure Switches

The RT Pressure Switches series includes pressure-operated switches with a single-pole changeover contact, where contact position is determined by the inlet pressure and the selected setpoint. The series is intended for industrial and marine refrigeration applications and includes versions for pressure control, neutral zone regulation, and specialized PLC-oriented switching functions. These switches are built for use with alternating or direct current and are offered with interchangeable contact systems, multiple enclosure options including high-protection versions, and models designed for both low-pressure and high-pressure duties. The series is also associated with wide regulating ranges, compact construction, and certifications that support use in safety-related applications, including versions rated to SIL 2. Overall, the RT Pressure Switches family is designed for refrigeration pressure monitoring and control tasks that require durable switching performance, application-specific variants, and compatibility with industrial operating conditions.
