Abstract
A casing includes a base, a trigger switch, an alarm device, and a cover. The base includes a first side plate and a second side plate perpendicular to the first side plate. The trigger switch is mounted to an inner side of the first side plate. A resilient tab is formed on a top of the trigger switch. The alarm device is electrically connected to the trigger switch. The cover covers on a top of the base and deforms the resilient tab down. A recess is defined in a bottom surface of the cover and located between the second side plate and the resilient tab. When the cover is slid away from the second side plate, the recess aligns with the resilient tab. The resilient tab enters the recess and restores. The trigger switch triggers the alarm device to alarm.
