JSM/CJSM FRONT KEYPAD + LIGHTS, 4 BUTTONS

Description

The JSM/CJSM Front Keypad + Lights is a 4-button input device with integrated lighting, commonly used in industrial, security, and embedded system control. The lights provide visual feedback based on user interaction or system status.

Working Principle

• Each button acts as a momentary switch, sending a signal when pressed.
• Integrated LED lights offer visual status updates, such as indicating which button was pressed or showing operational states.
• The keypad connects to a controller (e.g., microcontroller, PLC) to process the signals.
• Buttons can be assigned to specific functions like navigation, selection, or control operations.

• Buttons: 4
• Lighting: Built-in LEDs for feedback or status indication
• Voltage: 3.3V, 5V, or 12V (system-dependent)
• Current: <100mA per button (LEDs may require additional current)
• Interface: Direct wiring, ribbon cable, or connector

Applications

• Industrial control systems
• Access control and security systems
• Embedded system interfaces
