Slide actuation allows easy setting during assembly or field service. 4 positions provide 16 binary combinations for address selection, mode configuration, or option setting.","working_principle":"Each position is an independent SPST slide switch. Sliding the actuator moves a contact between the open and closed positions. Gold-plated contacts ensure reliable low-level switching for logic signals.","pin_description":"
