Description
Global offers the Tecmark 4000 Series 25 Amp Pressure Switch featuring a durable plastic construction with 1/8th" MPT standard threads and dual spade connectors for simple two-wire installation. This versatile pressure switch provides universal compatibility with Balboa, Gecko, ACC, Hydroquip, Len Gordon, Maddux, and virtually all standard spa heater tubes. The exceptional 25 Amp rating makes this switch ideal for 115V plug-in configurations where heater hot wire routing passes directly through the switch—a specification rarely available in standard pressure switches. While typical air button pressure switches handle minimal relay loads under 1 Amp, this robust model accommodates both heavy-duty 25 Amp and light-duty 1 Amp systems with equal reliability. Common failure symptoms include switch contacts failing to close when circulation pumps activate and create system pressure, or contacts remaining closed after pumps deactivate. Either condition typically triggers no-heat conditions or overheat situations in most spa control systems. Before replacing your pressure switch, verify proper pump operation and clean filters, as blocked flow paths can mimic pressure switch failures and generate flow error codes. This higher-amperage switch offers backward compatibility with lower-amperage applications, whereas standard 1 Amp switches cannot substitute in 25 Amp installations.
