Traffic safety equipment provides visible and physical barriers or high visibility guidance systems to help control traffic flow.

Pushbutton switches are mechanical switches defined by the method used to activate the switch. The activation method is typically in the form of a plunger that is pushed down to open or close the switch.

Bar graph arrays are light emitting diodes (LEDs) that are used for solid state metering in applications such as audio monitoring, telecommunications, and instrumentation

Switches are devices that allow electric current to flow when closed and prevent current flow when opened. Switches, All Types are a high level search form that includes options for all switch types. Search forms for specific switch actuator types are also available.

Emergency stop switches are devices that users manipulate to initiate the complete shutdown of a machine, system, or process.

Optical time domain reflectometers (OTDR) measure the elapsed time and intensity of light reflected along an optical fiber. They are useful tools for locating problems in an optical network as they can compute the distance to breaks or attenuation

Electro-optic modulators are analog or digital devices that use an electric field to alter the characteristics (e.g., band gap and index of refraction) of a material through which light is traveling, changing the characteristics of the light itself

Industrial knobs are small, usually round, devices that are designed for use on industrial machinery, electronic components, and metal cabinetry. They are usually made out of metal, plastic, or rubber and are available in a variety of sizes, colors, and finishes.

Standard keypads are standard size membrane or carbon pill keypads.

Human machine interfaces (HMI) are operator interface terminals with which users interact in order to control other devices.

Fiber optic attenuators are devices that reduce signal power in fiber optic links by inducing a fixed or variable loss. They are used to control the power level of optical signals at the outputs of light sources and electrical-to-optical (E/O) converters. They are also used to test the linearity and dynamic range of photo sensors and photo detectors

Control grips are handles or similar devices with built-in control switches. The best known control grips are joy sticks with fire buttons.

Locks and locking systems are mechanical fastening devices designed to close and control access to doors, drawers, or containers. Common types of locks include cam locks, combination locks, deadbolts, padlocks, and key-operated locks.

Water valves are designed to handle and control hot water, cold water, ground water, potable water, salt water and/or wastewater. They are made from metal or plastic.

Tugs, tow tractors and pushers are used to move rolling items. They are wheeled, self-propelled, and capable of moving heavy loads.
