Latches are mechanical components that hold doors, drawers, or cabinets closed. There are several basic types of latches. Cam latches attach to the back of a lock or lock cylinder and rotate to block or restrict the movement of a component or door. Compression latches swing into a latching position and then compress a gasket and/or panel against a frame. Deadbolt latches have a lock bolt that extends into the door jam. Draw latches or tension latches pull surfaces together and hold them closed. Hasps, hinged metal straps that fit over a staple, are usually secured by a padlock or pin. Rotary latches have one or more rotating members and also called rotating catches, hooks, bear claw latches, and two-rotor latches. Slam latches allow doors, drawers, or cabinets to be pushed or slammed closed. Passenger restraint latches are designed and manufactured in accordance with Federal Motor Vehicle Safety Standard No. 206 (FMVSS 206) from the U.S. National Highway Traffic Safety Administration (NHTSA). This standard establishes requirements for side door locks and related components in order to minimize the likelihood that occupants will be thrown from a vehicle because of an impact.
