Please note that effective June 21, 2017 Antunes Controls sold their pressure switch line to Crossroads Industrial Services.
Our compact, sensitive Antunes JD-2 switches are made of rugged die-cast aluminum and feature adjustable set point, set-point indication and visible on/off indicator.
The Antunes JD2 series is available in five range scales and give you accuracy and reliability.
The original Chicago Safety Products switch was called the Model D-1. The Model D-1 was a differential air pressure switch developed primarily for the industrial combustion market. The D-1 air switch was used to sense air-flow across a burner.
The first customer was Despatch Industries in Minneapolis Minnesota with an order for 100 switches. Following a process of continuous improvement, the second generation of this air-flow switch was soon introduced. This model was called the JD-2. The model was named as the second (2) generation of the differential switch (D). What does the J stand for? Always a strong family man, August Antunes used this opportunity to name this product for his children, Jim and Jane.
