A Draeger ignition interlock device (red arrow) in a Scania bus. An ignition interlock device or breath alcohol ignition interlock device (IID or BAIID) is a breathalyzer for an individual's vehicle. It requires the driver to blow into a mouthpiece on the device before starting or continuing to operate the vehicle.
Consumer Safety Technology, LLC. was started in 1988, with their first ignition interlock system using alcohol-specific fuel cell technology developed in 1992. [1] They worked with Iowa State University engineers to develop this new technology. Intoxalock became registered in 2006 and in 2012, CST began officially doing business as Intoxalock.
Smart Start Inc. was founded and incorporated in September 1992 in Dallas–Fort Worth by Bettye Rodgers and Jay D. Rodgers under the name “1A Smart Start, Inc.” [1]. On August 21, 2015, 1A Smart Start, Inc. was acquired by ABRY Partners, becoming 1A Smart Start, LLC. [2]
EN 50436 is a series of European Standards for ignition interlock devices (also called 'alcohol interlocks') on motor vehicles.. An alcohol interlock consists of two main components: an instrument that measures breath alcohol via a mouthpiece inside the vehicle, and a control unit (normally installed under the dashboard) which controls the current supply to the vehicle's starter relay.
Trapped key interlock switchgear door. An interlock is a feature that makes the state of two mechanisms or functions mutually dependent. It may consist of any electrical or mechanical devices, or systems. In most applications, an interlock is used to help prevent any damage to the machine or to the operator handling the machine.

[22] [23] Muir demonstrates the close personal ties and professional alliances between Simeon North and neighbouring mechanics mass-producing wooden clocks to argue that the process for manufacturing guns with interchangeable parts was most probably devised by North in emulation of the successful methods used in mass-producing clocks.

The key can then be used to unlock the kiln door. While the key is removed from the switch interlock, a plunger from the interlock mechanically prevents the power switch from being turned on. Power cannot be re-applied to the kiln until the kiln door is locked, releasing the key, and the key is then returned to the power switch interlock. [5]
