Instructions for Use:

1. Installation:

   • Ensure that the leads are not bent sharply; use a gentle radius to avoid damaging the reed switch.
   • Solder the leads to your circuit board or wiring, ensuring that the soldering iron is set to a moderate temperature to prevent overheating.

2. Magnetic Actuation:

   • Place a magnet near the reed switch to close the contacts. The magnetic field should be strong enough to actuate the switch within its sensitivity range (25 to 60 AT).
   • Remove the magnet to open the contacts.

3. Electrical Connection:

   • Connect the reed switch in series with the load and power source. Ensure that the current does not exceed the maximum contact rating (5VDC @ 100mA).

4. Environmental Considerations:

   • Operate the reed switch within the specified temperature range (-40°C to +85°C) to ensure reliable performance.
   • Avoid exposing the switch to excessive humidity or corrosive environments, as this can affect its longevity and performance.

5. Testing:

   • Test the reed switch using a multimeter to verify continuity when the magnet is applied and when it is removed.
   • Check for any physical damage or signs of wear during regular maintenance.

6. Storage:

   • Store the reed switch in a dry, cool place away from strong magnetic fields to prevent accidental actuation.

7. Handling:

   • Handle the reed switch with care to avoid dropping or applying excessive force, which can damage the glass housing.

By following these instructions, you can ensure the optimal performance and longevity of the SW-277TR reed switch.
