Basically it requires that the signals to go to Stop and are checked before any changes can be made within the interlocking.
Originally it was mechanical, but these days its electronic.
Mechanical sensors work by converting a mechanical input (such as pressure, force, or displacement) into an electrical signal that can be measured and interpreted. They typically consist of a sensing element that deforms in response to the mechanical input, causing a change in electrical properties (such as resistance or capacitance) that is then detected by the sensor's circuitry. This electrical signal is then processed to provide a measurement or indication of the original mechanical input.
A car key fob uses radio frequency signals to communicate with the vehicle's receiver, allowing the user to remotely lock and unlock the doors. When the button on the key fob is pressed, it sends a signal to the receiver in the car, which then activates the door locks.

A timeball tower works by raising and lowering a large metal or wooden ball on a pole at a specific time each day to signal the exact time to ships in the harbor. The ball is typically raised at a set time (e.g. 1pm) and dropped precisely at the time of noon or 1pm to allow ship captains to synchronize their chronometers for navigation.
A lock and key system works by using specially designed grooves and ridges on the key that align with pins inside the lock. When the correct key is inserted, the pins are lifted to the right height, allowing the lock to be turned and opened. This mechanism ensures that only the correct key can operate the lock.
dude they use a tower to get signal then a satalite for service.
The auxiliary contact is to be utilized for interlocking of another relay or contactor or indication signal from another equipment.
I think you mean "why doesn't my key work to open or lock the doors?" If that IS what you mean, the key's battery sends a radio signal to the cars computer. The computer directs the door lock system to lock or unlock the doors, but it gets it energy to do that form the battery. Hence: Car battery dead - car's onboard computer cannot respond to directions from the key signal.
When you use an EMS or cell phone jammer a lower power radio signal is broadcast.this signal is capable of cutting off communication between the cell phone and its base tower.
The signal from the phone has to be in a line of site with a transmission tower. It can't go through a hill or other solid object.
Yes, its a burned out bulb. The dash light will always work and in the case of erratic flashing that is just an indication that it is in fact the bulb that is burned out.
Work Resumed on the Tower was created in 1984.
you need to remove the steering wheel, then the plastic dust cover on the column. then you have to compress the steering wheel lock plate and remove the snap ring. once this is done, remove the turn signal switch by taking out the 3 screws and removing the signal lever. then unscrew the hazard switch (if it has one just in front of and slightly below the ignition lock) pull the turn signal cam out far enough so you an access the ign cyl lock screw. remove the screw all the way out and the lock cyl will slide out. this will only work if your jeep is equipped with the GM style steering column and ign. lock cyl.
How EVDO works is very similar to a cell phone except you are surfing the web. The wireless access card receives a signal from a tower that allows you to connect to the internet.
The time of day doesn't matter but the distance from the nearest cellphone tower does. If the signal is too weak the phone won't work.
