The Button Ball Alarm Sensor is what you need if you want an alarm sensor for your doors and windows. It also comes in white and brown, so you can make it blend in with any decoration.

This alarm sensor is great for letting you know if someone has opened a door or window, giving you greater security. When you close the door or window, it compresses the button ball into the contact shell, which deactivates the alarm. When the door or window opens, the button ball extends and the alarm is activated. In the picture on the left, the sensor on the right has wire leads, while the sensor on the left has terminals that the existing wire is connected to.

This will work with any hardwired system or a wireless sensor that has terminals.

But if the Button Ball Alarm Sensor isn’t quite what you’re looking for, please take a look at our other hardwired contacts.
