I've been playing with these through hole reed switches: MDSR-4-12-23. It has been my experience so far that you have to be very careful in handling them, including when bending the leads to 90 degree angles for PCB insertion. It doesn't take much applied force to chip or crack the hermetically sealed capsule.
So my questions are two:
- Is there any advice for handling and lead-forming that I should instruct a PCB assembler about as part of my design package?
- Is the principle function of the reed switch as a magnetic switch compromised if the capsule seal is compromised?
