Touchless Switches Information
Touchless switches are switches that electrically open or close a circuit without physically touching the switch. Applications for touchless switches include medical facilities or hospitals and building entries.
Operation
The primary function of a touchless switch is to open or close electrical circuits without physical contact. These switches rely on infrared technology to complete the electrical actuation. The touchless switch operator is responsible for controlling circuitry.
Configurations
Touchless switches are commonly made of metal or plastic housing. Touchless switches are generally circular or rectangular in shape and are available in various colors and are mounted on a wall or a vertical surface. The most prominent components of a touchless switch are the switching function that controls the circuit, and operating distance that determines the range the switch is activated.
Specifications and Features
Specifications
The following specifications determine the functionality of a touchless switch.
- Operating Distance: The distance range the switch is activated.
- Voltage Range: The AC or DC voltage range the switch operates.
- Current Rating: The amount of current the switch is rated.
- Electrical Connection: The connection of the switch to the electrical circuit. For example: wire leads, screw terminals, quick connect, or blade.
Features
These features provide additional utility or ease-of-use.
- Illuminated Switch: A switch with an integral lamp that illuminates when the switch is connected to an energized circuit.
- Programmable: The switch is programmable.
- Weather Resistant/Waterproof: Sealed (hermetically) against moisture.
