C&K Switches SUM Ulta-Miniature Snap-Acting Switches
C&K Switches SUM Ulta-Miniature Snap-Acting Switches are single-pole, double-throw (SPDT) switches with a 3A maximum electrical load. C&K Switches SUM Ulta-Miniature Snap-Acting Switches have a 10,000- to 300,000-cycle electrical life, a 1 million-cycle minimum mechanical life, and 500VRMS of dielectric strength. The snap switches are designed for ultra-miniature space constraints and can be integrated into utility systems, medical equipment, and home appliances.
