SpaShopper offers this versatile Tecmark pressure switch designed for universal compatibility with digital spa control systems. This component includes 1/8" MPT standard threads and connects via 2 spade terminals for straightforward electrical hookup. The comprehensive brass adapter kit contains a 1/8" barb fitting, 1/4" barb fitting, plus 3/8" and 1/4" compression fittings to accommodate various plumbing configurations.
Compatible with heater assemblies from Balboa, Gecko, ACC, Hydroquip, Len Gordon, Maddux, and most standard hot tub manufacturers. This 1 Amp switch is engineered for low-current digital control systems where minimal electrical load passes through the pressure sensing mechanism.
This switch monitors water flow by responding to pump pressure—closing the circuit when your circulation pump activates and opening when the pump stops. Flow error codes typically indicate switch failure, though clogged filters or pump malfunctions can produce identical symptoms. Proper diagnosis is essential before replacement.
Important Application Note: This 1 Amp model is NOT suitable for air button systems where heater power routes directly through the switch (typically 115V configurations requiring 20-25 Amp rated switches). Those applications are uncommon and require heavy-duty alternatives.
Critical Warning: Do not attempt field adjustment of pressure settings—doing so voids the manufacturer warranty. Switch adjustment rarely solves underlying system issues and typically indicates separate problems requiring professional diagnosis.
