Siemens 3SX3-127 Limit Switch Head Lever Actuator

The Siemens 3SX3-127 Limit Switch Head Lever Actuator is a fork‑lever actuator head designed for use with Siemens 3SX3 limit‑switch bodies, providing a precise mechanical interface that translates motion from a fork lever into a switch trip. Identified by the 3SX3-127 designation, this lever‑actuator head is the active head component in the Siemens Furnas Electric Co. 3SX3 family, enabling fork‑lever actuation in automation circuits. It is used in industrial automation and machine guarding applications where fork‑lever actuation is required to trigger the limit switch, supporting reliable triggering in equipment such as conveying systems, presses, and assembly lines. The head features a fork‑lever configuration and is intended to be paired with a compatible 3SX3 switch body for correct engagement with the lever and consistent actuation of the switch contacts. When selecting this head, confirm compatibility with your 3SX3 limit switch body to ensure proper mechanical engagement and reliable operation within your control system.
