This Gecko DTEC-1 pressure switch detects water pressure in spa or pool heater systems, closing the circuit at 2PSI to protect the heater against overheating. It features a single-pole single-throw (normally open) switch, 1Amp capacity, and a 1/8" NPT male threaded connection. Compatible with Gecko M-Class/S-Class Pack, as well as a number of other heaters.

Replaces several OEM versions including 510AD0167, 510AD0249, and 34-0178C-K.

The switch's compact design and standard spade terminals make it easy to install; thread sealing tape is recommended to avoid leads. This is a upgraded model from the previous version with a plastic housing, now in a durable metal casing for improved durability..
