Abstract
A swing bolt lock mechanism for preventing false status switch enabling is described. The lock mechanism is a swing bolt lock mechanism wherein the swing bolt has an inner ramp wall against which a blocker rod is spring-biased. A ramp extension arm is displaceably secured with the swing bolt and provides an extension of the ramp wall whereby the blocker rod may only be displaced when the swing bolt is at its fully locked position whereby to arrest the swing bolt at that position. The displacement of the blocker rod also toggles a lock status switch to provide an indication that the lock is at its locked position. Accordingly, the lock status switch cannot be prematurely actuated.
