Hidden ignition or fuel pump kill switches were once popular and could be installed quite easily. Today, many cars have anti-theft systems built in.
The electric immobiliser/alarm system was invented by St. George Evans and Edward Birkenbeuel and patented in 1919. [2] They developed a 3x3 grid of double-contact switches on a panel mounted inside the car so when the ignition switch was activated, current from the battery (or magneto) went to the spark plugs allowing the engine to start, or immobilizing the vehicle and sounding the horn.

If the system is "non-latching" (i.e., it does not stay off after the car is switched off), the EPA only calculates fuel economy figures when the system is engaged.
The starter motor is a series, compound, or permanent magnet type electric motor with a solenoid and solenoid operated switch mounted on it.

If sufficiently shocked, the cage will spring open which actuates an associated switch. The switch is reset by pressing the cage closed through the flexible (red) top cover, retrapping the mass. These switches are also used to open a contactor (a large relay) to disable the high power circuit of a battery electric vehicle upon collision.
