For replacing mercury and pendulum switches, the DSB Series mercury-free tilt sensor switches meet product-safety concerns due to normally closed (on) status. Through hole, PCB-mount devices, the series uses a photo interrupter instead of conventional contacts to ensure reliability and sensitivity to very small angle changes. The switches contain two solid-state devices: an infrared LED and a photo transmitter. A nickel-plated ball rests at the focus point when the switch is level. Ball movement allows functionality of 360° circumference rotation and the switch is triggered when tilted beyond ±30° from the horizontal. NKK SWITCHES, Scottsdale, AZ. (480) 991-0942.
