The IKN0403000 is a four-way, surface-mount (SMT), low-profile dual in-line switch from the IKN series. It features self-cleaning wiping contacts with an initial contact resistance of 30 mΩ maximum and is rated for a switching current of 100 mA at 24 VDC. This switch is designed for a long electrical life of 2,000 cycles and operates over a wide temperature range from -40°C to +100°C. Its SMT design and low profile make it suitable for space-constrained PCB applications requiring manual configuration or setup.
