It provides one normally-open and one normally-closed contact pair (1 NO + 1 NC), with the NO on terminals 53/54, the NC on 41/42 on the left side, and a second NC on 21/22 and NO on 33/34 on the right side — giving you two isolated current paths: one NC, one NO. Termination is via spring-loaded (cage-clamp) terminals, which holds the wire without retorquing — useful in high-vibration nacelle environments where screw terminals can loosen over time. ## Integration notes Mounts laterally on the left or right side of a 3RT2.1 contactor — no extra DIN rail space needed; it clips directly onto the contactor's side profile. The 75 x 65 x 20 mm package dimensions mean it adds minimal width to the contactor stack — keeps the panel fill factor tight.","metaTitle":"3RH2911-2DA11-Z W97 auxiliary switch, 1 NO + 1 NC, spring-lo","metaDescription":"Siemens 3RH2911-2DA11-Z W97 auxiliary switch for 3RT2.1 contactors. 1 NO + 1 NC, spring-loaded terminal, lateral mounting.
