Electrical Engineering/Household letters box with mechanical combination Lock.


Dear Prof Cleggsan

Is it possible to design and Construct household letters box with mechanical combination Lock?.


Yes, of course it is possible to design and make letter box with combination locks of various kinds.

But, why would you want one?  Electronic mechanisms are more prevalent now days and passwords are more popular. In fact, locks with key may be more desirable.

But, for post office boxes, we must think of the postal delivery services being able to easily get the box open and closed to deposit the mail.  This is done now in apartment mailboxes which are open in the back and the postal worker has a key to the door entry to that gives access to the room behind the boxes.

But for single resident boxes it must be easier.  Electronic systems may be more suitable solution.
