You are installing one of the finest switches of its type 

on the market. Design of this switch is based on the 

same principles of sensitivity, accuracy and dependability 

that have made Antunes Controls Air Flow Switches so 

successful. These switches are fully approved. They are 

UL listed and recognized for the U.S. and Canada, and 

approved by Factory Mutual (FM).

The switch is adjustable within its range, as shown on the 

range scale located on top of the unit.

The Model JD-2 is sturdy, compact and cost effective. 

All components are well made. The switch is neat in 

appearance with a die cast aluminum electrical housing. In 

every way you will be pleased with the ease of installation 

and the reliability of your Antunes Controls JD-2 Switch.
