## Customer Reviews

### ⭐⭐⭐⭐⭐ 







  
  
    Works Well
  

*by P***A on Reviewed in the United States on July 12, 2021*

We just installed this today on the inside track of a sliding door as an alarm contact and it works perfectly as described.

### ⭐ 







  
  
    This is not a N/O N/C ball switch
  

*by P***9 on Reviewed in the United States on January 29, 2022*

This is just like 4 other switches I own for use in alarm systems, what I thought I was buying was a door light switch?  The third terminal is for an end of line resistor required for all CMOS input alarm systems, not a normally open when closed door switch.

### ⭐⭐⭐⭐ 







  
  
    It's effetive
  

*by K***R on Reviewed in the United States on August 11, 2018*

The item resolved issue with our alarm system when the wires were inadvertently cut during a construction project.  The new button reconnected the alarm.
