Abstract

A security alarm with a wired remote triggering device consists of a triggering switch with two spring blades and a flexible sleeve tube holding both spring blades together. The security alarm with a strap is hung on the doorknob inside a door or placed inside a drawer, and the triggering device is set up from outside of the door or the drawer by pulling off the flexible sleeve tube. The two spring blades will thus be clipped in a gap between the door and its frame to keep the alarm circuitry open. When any unauthorized person opens the door or the drawer, the triggering device will fall off from the gap; thus the two spring blades will automatically open to keep the alarm circuitry in close status so as to activate the alarm, so the theft deterrent purpose is consequently achieve.
