Which device makes or breaks a circuit if the gambling machine is tilted or tampered with and triggers an alarm?

• A. topper
• B. voucher
• C. tilt switch
• D. video lottery terminal (VLT)

Answer: (C)

The device relied on here is a tilt switch. It’s a small sensor that changes the electrical circuit based on the machine’s orientation. Inside, a conductive element like a tiny ball or drop moves with gravity: when the machine is upright, the element completes the circuit, but if someone tilts or tampers with the machine, the element shifts away and the circuit opens or triggers an alarm. That immediate change in the electrical state alerts security or disables the machine, helping prevent tampering or tipping.

The topper is just a decorative piece and doesn’t detect tampering. A voucher relates to payout or tickets, not encasing a tamper alarm. A video lottery terminal is the entire gaming device, not a specific tamper-detection component.
