The "plumb-bob" tilt for [1] is dependent on a conical weight hanging on a rod, surrounded by a brass ring. Raising the weight higher or lower makes the tilt more or less sensitive by changing the distance between the cone and ring. Many operators adjust this and fail to fasten it tightly enough and the cone falls into the cabinet. The "slam tilt" switch for [2] is a leaf switch with a small intertial counterweight on one of the leafs and rarely falls apart. Funny enough, modern slot machines still call a tamper or intrusion event a "tilt".
