Welding reed switch

Often, a reed switch has to be soldered or welded. Reed switches are usually plated with suitable solderable plating. Welding is also quite easy on the nickel/iron leads of the reed switch. However, both, if not carried out properly, can cause stress, cracking, chipping or a rupture in the reed switch. When soldering or welding, it is best to keep as far away from the glass seal as possible. This may,...
