Armstrong International FS6502-795 Pressure Switch

Armstrong International FS6502-795 Pressure Switch (38094B004) is a pressure-activated control device from the Armstrong Tridelta line, designed to sense a monitored pressure and trigger an electrical change when the preset point is reached. This part is used within Armstrong-based control architectures to automate responses such as starting or stopping pumps, opening or closing valves, or sounding alarms in industrial process or HVAC-related systems that rely on reliable pressure monitoring. The FS6502-795 designation identifies the exact configuration within Armstrong’s catalog, helping technicians verify compatibility during maintenance or replacement of Tridelta equipment. With the part number 38094B004, this switch can be matched to existing installations that require the FS6502-795 service part, ensuring continuity with other Tridelta components and established safety interlocks. In practice, pressure switches like this provide a simple, robust means to translate fluid or gas pressure into a discrete electrical signal, enabling automated control and protection of piping networks, boilers, or processing lines that depend on stable pressure management.
