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 decor.

This alarm sensor is great for letting you know if someone has opened a door or window. When you close the door or window, it compresses the button ball into the contact shell, which deactivates the alarm. But when the door or window opens, the button ball extends and the alarm activates.

But if this isn’t quite what you’re looking for, please take a look at our other hardwired contacts.
