Internal Mechanisms
- A relock trigger, or internal relocker, is an integral part of the combination lock itself. It is usually designed to activate when the dial spindle is punched through. The trigger may consist of a spring-loaded lever or plunger that engages the bolt when the back cover is dislodged from the lock case. Some combination locks also are equipped with a thermal relock trigger that activates in the event of a torch attack. Nearly all safes made after World War II have relock triggers in their combination locks.

Famous quotes containing the word internal:
“The real essence, the internal qualities, and constitution of even the meanest object, is hid from our view; something there is in every drop of water, every grain of sand, which it is beyond the power of human understanding to fathom or comprehend. But it is evident ... that we are influenced by false principles to that degree as to mistrust our senses, and think we know nothing of those things which we perfectly comprehend.”
—George Berkeley (1685–1753)
