A limit switch with a roller-lever operator; this is installed on a gate on a canal lock, and indicates the position of a gate to a control system A limit switch mounted on a moving part of a bridge In electrical engineering , a limit switch is a switch operated by the motion of a machine part or the presence of an object.
A system for this purpose is known as a stick pusher. The safety requirements applicable to fixed-wing aircraft in the transport category , and also to many military aircraft, are relatively demanding in the area of pre-stall handling qualities and stall recovery.
Basic aircraft control surfaces and motion. A)aileron B)control stick C)elevator D)rudder. Aircraft flight control surfaces are aerodynamic devices allowing a pilot to adjust and control the aircraft's flight attitude. Development of an effective set of flight control surfaces was a critical advance in the development of aircraft.
A control system manages, commands, directs, or regulates the behavior of other devices or systems using control loops. It can range from a single home heating controller using a thermostat controlling a domestic boiler to large industrial control systems which are used for controlling processes or machines.
An inspector's switch, which places the elevator in inspection mode (this may be situated on the top of the elevator) Manual up/down controls for elevator technicians, to be used in inspection mode, for example.
Typical trim tabs on aileron, rudder and elevator. Trim tabs are small surfaces connected to the trailing edge of a larger control surface on a boat or aircraft, used to control the trim of the controls, i.e. to counteract hydro- or aerodynamic forces and stabilise the boat or aircraft in a particular desired attitude without the need for the operator to constantly apply a control force.
A governor, or speed limiter or controller, is a device used to measure and regulate the speed of a machine, such as an engine.. A classic example is the centrifugal governor, also known as the Watt or fly-ball governor on a reciprocating steam engine, which uses the effect of inertial force on rotating weights driven by the machine output shaft to regulate its speed by altering the input flow ...
MULTI is the first cable-less elevator developed by TK Elevator (formerly ThyssenKrupp Elevator). Rather than using cables to lift the elevator, MULTI uses linear motors. [1] As well as moving vertically between floors of a building, MULTI can also move horizontally through a floor of a building. MULTI is being tested at Rottweil Test Tower. [2 ...
