Button and signal light series products are indispensable components in industrial control and automation systems, mainly used for human-computer interaction, status indication and operation control. The following are their main uses and classifications:
1. Button series products: A button is a manually operated control element used to send start, stop, reset and other instructions. Common button types include:
1. Main uses
● Start/stop control: used to control the start and stop of motors, equipment or systems.
● Emergency stop: The emergency stop button (emergency stop button) is used to quickly cut off the power supply or stop the equipment in an emergency.
● Reset operation: used to reset the equipment or system status.
● Mode selection: select different operation modes through multi-position buttons.
● Signal input: pass the operation instructions to PLC, inverter or other control devices.
2. Common types
● Normally open button (NO): connects the circuit when pressed and disconnects when released.
● Normally closed button (NC): disconnects the circuit when pressed and connects when released.
● Self-locking button: maintains the state after pressing and resets when pressed again.
● Emergency stop button: with locking function, it needs to be manually rotated to reset after being pressed.
● Waterproof button: suitable for humid or outdoor environments.
● Explosion-proof button: used in flammable and explosive environments.
3. Application scenarios
● Industrial control cabinets, operating tables
● Mechanical equipment, production lines
● Elevators, cranes
● Automation systems
2. Signal light series products: Signal lights are used to indicate the operating status of equipment or systems, usually transmitting information through different colors and flashing methods.
1. Main uses
● Status indication: Display the operating status of the equipment (such as running, stopping, and failure).
● Alarm prompt: Prompt abnormal conditions through flashing lights or color changes.
● Operation feedback: Indicates whether the operation is successful (such as the response after the button is pressed).
● Safety warning: Remind the operator of potential dangers.
2. Common types
● Monochrome signal lights: single color (such as red, green, and yellow), used for simple status indication.
● Multicolor signal lights: a combination of multiple colors, which can indicate multiple states.
● Sound and light alarm lights: Combine sound and light for emergency alarm.
● LED signal lights: Energy saving, long life, high brightness.
● Explosion-proof signal lights: Used in hazardous environments.

Button and signal light series products play an important role in industrial automation and electrical control. Reasonable selection and use can improve the safety and operating efficiency of the system.
