A window safety and security device detects unauthorized movement of a double-hung window upon which the device is installed and communicates an alarm in response to the detecting. The device includes a single, high-powered suction cup with a housing configured to be removably attached to an inside glass pane of a first sash of the double-hung window formed with a first and a second sash, a first electrical switch including an actuator that toggles the switch contacts between an open or non-conducting state to a closed or conducting state when armed (powered) in a case where part of the window contacts and depresses the actuator. The device also includes a light or buzzer, which are activated when the first switch is caused to conduct. Preferably, a second electrical switch is included for "arming" and "disarming" the device. |
