Reed Switch Modification
Reed Switch modifications can be very dangerous to the Reed Switch if not done properly. Primarily, this is because the reed lead is large by comparison to the glass seal. Here a balance is achieved in Reed Switch sensitivity and mechanical strength. If the lead of the Reed Switch was much smaller than the glass, seal stress and glass breakage would not be an issue. However, to achieve the sensitivity and power requirements in the Reed Switch, a larger lead blade is necessary. With that in mind, it cannot be emphasized enough, any forming or cutting of the Reed Switch leads must be done with extreme caution. Any cracking or chipping of the glass are signs that damage has occurred. Internal damage can occur with no visible signs on the seal. In these instances, seal stress has occurred, leaving a torsional, lateral, or translational stress in the seal. This produces a net force on the contact area that can affect the operate characteristics (Pull-In and Drop-Out), contact resistance, and life characteristics.
Many times the user will often choose to make their own modifications, and only after manufacturing and quality problems with the product, do they go back and choose the approach of letting the Reed Switch manufacturer perform the value added requirements.
Being a manufacturer of reed switch, reed relays and reed sensors MEDER understands the need for modifications. In fact over 60% of the product MEDER sells are actually modified in some way
