How a Snap Mousetrap Works - Diagram & Mechanism Explained #2020130 (License: Personal Use)

This schematic depicts a classic wooden-base snap mousetrap in its armed state, featuring a coiled spring, U-shaped striking bar, bait pedal, and holding arm. The tensioned spring is held in place by a thin metal rod resting on the pedal; when disturbed, the rod slips, releasing the bar with lethal force. The design emphasizes reliability, simplicity, and rapid response for rodent control.
