Reed Switch Formation Tolerances

Modifying the leads of reed switches is a very delicate process and should be carried out by special tools which do not transfer shock into the contact or shift the sensitivity. We have the necessary tools to modify reed switches to the following formation, within the specified tolerances to suit different applications.

Cropped Reed Switch

drawing_tolerances_croppedThe leads are gripped just outside the glass seals to prevent shock from transferring to the contacts, and the unwanted leads are cropped in one swift motion. Cropped reed switches can be used for soldering longer wires for encapsulation in customized housings or on SMD PCBs with slots.

 

 

 

SMD Formed Reed Switch

drawing_tolerances_SMDThe leads are gripped just outside the glass seals, cropped to the required length, and then SMD formed. No flattening (which needs extra pressure that could damage the contacts) takes place as all reed switches are produced with flat leads. As a result, SMD formed reed switches have oriented internal blades for maximum in-group sensitivity. These devices are a cost effective solution to SMD reed sensors for applications without shock and vibration.

 

Goal-post Reed Switch for Horizontal Mounting

drawing_tolerances_goalpostThe leads are gripped just outside the glass seals to prevent shock from transferring to the contacts, cropped to the require length, and then goal post formed. Blades are always oriented perpendicular to the formed leads for maximum in-group sensitivity. These devices are a cost effective solution to PCB mountable reed sensors for applications with stable environmental conditions.

 

 

Welded Reed Switch for Vertical Mounting

drawing_tolerances_weldedThe leads are gripped just outside the glass seals to prevent shock form transferring to the contacts, cropped to the required length, and then L formed. The L formed assembly is welded to a non-magnetic wire and the final assembly is lead out plated for solderability after welding. These kinds of reed switches are suitable for vertical PCB mounting.
