See Appendix for package dimensions Note on Availability of Products NVE keeps about 25 of the most popular types of GMR Switch products in stock at our manufacturing facility. However, because there are over 100 different varieties of GMR Switch parts, some part numbers may require a 6 to 8 week lead time before production quantities are available.
