148 Words1 Pages
Interlocking is a method of preventing undesired states in a state machine, which in a general sense can include any electrical, electronic, or mechanical device or system. In most applications an interlock is a device used to help prevent a machine from harming its operator or damaging itself by stopping the machine when tripped. Mechanical interlocking Interlocks may be strictly mechanical, as in the internal safety of a firearm that prevents release of the firing pin unless the chamber is properly closed. In the operation of a device such as a press or cutter that is hand fed or the work piece hand removed, the use of two buttons to actuate the device, one for each hand, greatly reduces the possibility of operation endangering the operator.
