LV-1925 Reed Switch for Line Voltage switching

  • Drawing of LV-1925 Reed Switch
  • Drawing of LV-1925 Reed Switch for Soldering
  • Drawing of LV-1925 Reed Switch for SMD mounting
  • Drawing of LV-1925 Reed Switch for Horizontal mounting
  • Drawing of LV-1925 Reed Switch for Vertical mounting


Contact Rating Configurable. Ruthenium contact. 20.0 mm Glass length. Normally Open. Inert gas filled. 4 types of Lead Formations.


Omni-polar. Does not require power for operation. Sputtered Contact. RoHS Compliant. Not ESD Sensitive.


The LV-1925 is designed for endurance at switching line voltage loads of 230VAC. Two versions are capable of switching 30W and 60W. When used with contact protection, direct switching of tungsten filament lamps is possible. The cropped version is suitable for smaller plastic housings and can be soldered to cables, the SMD version is suitable for reflow on PCBs, and the vertical and horizontal mount versions are suitable for mounting on through hole PCBs.
