1. Thread broken detection alarm control
The two-location switch thread broken detection is developed and designed specially for the user of the computerized embroidery machine. The product has automatic patching function, which simplify the multifarious operations after thread broken.

Main characteristic:
It has high integration. It decreases dialing switch time and depresses failure frequency. After thread broken and back, the machine can begin to patch automatically. Red, green and white three color LBD switch super lightness display many conditions of head running .it adapts broadly, such as 6 needles, 9 needles and different size clamping thread seat.

2. Bottom thread detection alarm control
The bottom thread detection alarm system is designed for the inconvenience during the embroidery. It gets rid of the unnecessary and repeating operation while the bottom thread cannot be detected. This function depresses working intensity and enhances production efficiency.

Main characteristic:
The bottom thread detection alarm is precise and with low failure frequency .it can operate with three-location and two-location switch thread broken detection board .it adapts to many installation modes with different needle number and different size clamping thread seat.

3. Needle position detection alarm control
Hall element needle position detection system is the foremost developed and most widely used mechanical&electronic sensor parts for needle position detection. After years of restructuring and deriving, it becomes the detection equipment that has the highest dependability, largest output and general trust.

Main characteristic:
Rheostat needle position detection system has integrates needle position detection and coding, which is controlled by single CPU. It lets rheostat circumgyrate through mechanical gearing .it makes needle position detection much more precise by judging the needle position through the change of both resistance value and needle position.

Main characteristic:
It is the same with upwards of 9 needles embroidery. The color-changing motor can be selected between 2-phase stepping motor and single-phase AC motor. (Note: the color changing by 2-phase stepping motor only adapts to the embroidery machines with less than 2 heads.)
