Pilot Light & Signalling Devices

Pilot devices are primarily used in commercial or industrial applications that require human-machine interface. Selector switches, pushbuttons or push button switches, pilot lights, signal beacons, and toggle switches are examples of these. Pilot devices are classified into two types based on their designs: indication devices and actuation devices. Furthermore, some devices provide both indication and actuation (ex: illuminated pushbuttons). These devices, which are typically used as part of a system, automated process, or control panel, provide information on the condition and control monitoring of various types of processes, machinery, and equipment.

Based on their construction, pilot devices are primarily classified as modular or compact. Modular devices are constructed in a way where each individual component can be chosen and configured for a unique purpose. Modular pilot devices offer significant features like pre-wiring and are highly customizable and adaptable. They are suitable for use in industrial environments and are frequently designed to meet UL-type ratings 1, 3, 3R, 4, 4X, 12, and 13. 30 mm and 22 mm are the most common sizes. Compact devices help OEMs save space and reduce operational costs. These compact devices, which have all-in-one designs, have limited functionality. Compact pilot devices, unlike modular designs, do not have the flexibility of multiple configurations and have unique part numbers.

The five most common types of pilot devices are:

• Pushbuttons
• Pilot lights
• Selector switches
• Emergency stops for emergency stop stations
• Potentiometers

Push button switches

Push button switches come in a variety of operator designs, including flush, extended, and mushroom heads, as well as with and without illumination. Normally closed, normally open, or combination contact blocks are typically provided with these devices. Push button switches are control devices that allow you to manually close and open a group of contacts.

Pilot lights

Pilot lights as indicated in the name are used for visual indication of the status of operation of a circuit, used mainly in applications for Stop/Run function indication, changing conditions, and alarm signalling. Pilot lights are also available in a variety of designs as indicators, replaceable lamp indicators and nonreplaceable indicators.

Electrical Selector Switches

Selector switches are rotary devices are used to manually close or open contacts. Selector switches differ from pushbuttons only in their operation. They are typically available in spring return, maintained, or key-operated designs. Selector switches have levers or knobs that can be rotated to open or close contacts, whereas pushbuttons operate linearly and have buttons for the same function. The contact blocks on selector switches and pushbuttons are typically interchangeable. These switches make it simple to select one or more options, such as hand-off-automatic, high or low speed, run or stop, and up or down. Selector switches come in two-, three-, and four-position configurations.

Emergency Stop Stations

Emergency stops are constructed to reinforce the safety of all machinery and personnel. These emergency stops are required by relevant codes and standards of installation for disconnecting and thereby disabling a system in the event of an emergency. They are also called emergency stop pushbuttons and are seen in designated emergency stop stations as either of the popular two types, push-pull, and push-twist release.

Potentiometers

Potentiometers are devices that feature three-terminal resistors with rotating or sliding contacts, which adjust the voltage sent to the machine.
