LV-1925 Reed Switch for Line Voltage switching

The LV-1925 is a Line Voltage Reed Switch is designed for endurance at switching line voltage loads of 230V. Two versions are capable of switching 30W and 60W loads at 230V. When used with contact protection, direct switching of tungsten filament lamps is possible. The cropped version of this Line Voltage Reed Switch 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.
