Handling of Reed Switches in Various Sensor Applications 5.2.4.1 Cutting and Bending of a Reed Switch... 

Fig. 5.15 Properly supported the switch lead while cutting is required, otherwise damage can occur to the reed switch.

Most reed switch suppliers can perform value-added cutting and shaping of the leads in a stress-free environment, using proper tools and equipment This is often the most economical approach for users, although it may not seem so at the time. 

Often, users will choose to make their own modifications, and only when experiencing manufacturing and quality problems with the product will they go back to the reed switch manufacturer and let him carry out the desired modifications. In Figs 5.14 and 5.15, the proper approach for cutting and/or bending the reed switch is shown. The effect on the pull-in and drop-out characteristics of cutting and bending the reed switch will be explained in more detail later.
