SpaShopper offers this Tecmark 4000 Series 25 Amp Pressure Switch engineered with durable plastic housing and equipped with 1/8" MPT standard threading plus dual spade terminals for wire attachment.

Universal compatibility includes Balboa, Gecko, ACC, Hydroquip, Len Gordon, Maddux, and virtually all standard spa heater tubes. The exceptional 25 Amp rating makes this switch uniquely suited for specialized applications.

Designed primarily for 115V plug-and-play configurations where hot wire heater circuits route directly through the switch. Standard air button switches typically handle less than 1 Amp relay signals, making this high-amperage model essential for specific installations.

Common failure symptoms include switches that fail to close under pump pressure or won't open when pumps cycle off, resulting in no-heat conditions or dangerous overheating scenarios. Before replacement, verify your pump operates correctly and filters aren't clogged, as these issues can mimic pressure switch failure.

This versatile 25 Amp switch functions flawlessly in both high-amperage and low-amperage (1 Amp) systems, whereas standard 1 Amp switches only operate properly in low-amperage applications.
