DAOKI JL012-13.5-2 Micro Limit Switch Instruction Manual

1. Konec produktuview

The DAOKI JL012-13.5-2 Micro Limit Switch is a compact, momentary action switch featuring a hinge lever actuator and a 3-pin SPDT (Single Pole Double Throw) contact configuration, providing both Normally Open (NO) and Normally Closed (NC) contacts. Designed for various electronic applications, these switches are rated for AC 125V at 1A.

Mezi klíčové vlastnosti patří:

• Momentary Action: The switch returns to its original state when the actuator is released.
• Hinge Lever Actuator: Provides a mechanical advantage for activation.
• SPDT Contacts: Offers flexibility with 1 Normally Open (NO) and 1 Normally Closed (NC) contact.
• Odolná konstrukce: Designed for a long operational life of over 500,000 cycles.
• Všestranná aplikace: Suitable for home appliances, audio equipment, toys, computer mice, business machines, communication devices, and Arduino projects.

2. Nastavení a zapojení

Proper setup and wiring are crucial for the correct function of the micro switch. Refer to the technical diagrams for pin identification and dimensions.

Konfigurace 2.1 pinů

The switch features three pins:

• Běžné (COM): The central pin, which connects to either NO or NC depending on the switch state.
• Normálně otevřený (NE): This contact is open (no connection to COM) when the switch is at rest and closes (connects to COM) when the actuator is pressed.
• Normálně zavřeno (NC): This contact is closed (connected to COM) when the switch is at rest and opens (no connection to COM) when the actuator is pressed.

2.2 Montáž a připojení

1. Montáž: Secure the micro switch in the desired position using appropriate fasteners or adhesives. Ensure the hinge lever is positioned to be actuated by the intended mechanism.
2. Pájení: Connect wires to the pins using solder. The pins are designed to withstand standard soldering temperatures. Apply heat briefly to avoid damage to the switch body.
3. Integrace obvodů: Integrate the switch into your circuit based on whether you require a Normally Open or Normally Closed function. For NO operation, connect your circuit to the COM and NO pins. For NC operation, connect to the COM and NC pins.

3. Návod k obsluze

The DAOKI micro switch operates as a momentary contact switch. When the hinge lever is pressed, the internal contacts change state. When the pressure is removed, the lever returns to its original position, and the contacts revert to their initial state.

• Aktivace: Apply force to the hinge lever to activate the switch. The operating force is approximately 70 ± 20gf.
• Contact Change: Upon actuation, the connection between COM and NC breaks, and the connection between COM and NO establishes.
• Uvolnění: When the force on the hinge lever is removed, the switch returns to its default state: COM and NC reconnect, and COM and NO disconnect.

4. Údržba

DAOKI micro switches are designed for reliability and generally require minimal maintenance. However, adhering to best practices can extend their lifespan and ensure consistent performance.

• Podmínky prostředí: Operate the switches within the specified temperature range of -25°C to 65°C and relative humidity below 85%.
• Čistota: Keep the switches free from dust, dirt, and moisture, which can interfere with the actuator mechanism or contact integrity.
• Vyhněte se nadměrné síle: Do not apply excessive force beyond the specified operating force to the hinge lever, as this can cause mechanical damage.
• Proper Soldering: Ensure soldering is done correctly to prevent cold joints or damage to the plastic housing. The pin-type package includes plastic to prevent solder flux infiltration.

5. Řešení problémů

If you encounter issues with your DAOKI micro switch, consider the following troubleshooting steps:

• Bez změny kontaktu:
  • Verify that the actuator is being fully depressed.
  • Check for proper wiring connections to the COM, NO, and NC pins.
  • Inspect for any physical damage to the hinge lever or switch body.
• Přerušovaný provoz:
  • Ensure all solder joints are secure and free from corrosion.
  • Check for stable power supply and load connections.
  • Confirm the switch is operating within its rated voltage a aktuální limity.
• Fyzické poškození: If the switch housing is cracked or the lever is bent, replacement is recommended.
