Frequently Asked Question
How does the photo booth coin mechanism work?
Reviewed by Booth Beacon · Verified 2026-08-25
Quick Answer
A mechanical coin mechanism (such as a Coinco or NRI validator) measures the physical diameter, thickness, weight, and magnetic conductivity of inserted coins, rejecting foreign tokens and triggering an electrical microswitch that starts the motor.
Full Answer
When valid coins pass through the mechanical rejector cradles, they trip a low-voltage microswitch. This switch energizes a holding relay, powering the main 110V/220V AC drive motor which starts rotating the master camshaft.
