# ANSI/IEEE Cam-operated limit switch form Canonical URL: https://eloragrid.ai/symbols/ansi-cam-operated-limit-switch Publisher: Elora Grid Updated: 2026-10-28 Lookup label: LS CAM Drawing use: Schematic Reference families: IEEE / ANSI, Manufacturer ## Symbol convention Convention: IEEE / ANSI Form: Limit Switch Normally Open - Cam Driven Autodesk IEEE Symbol Preview: Limit Switches, block HLS11S13. Matching functional counterpart linked separately. Independently drawn educational geometry; not a certified IEEE glyph or database identifier. Related representation: [Cam-operated limit switch](https://eloragrid.ai/symbols/cam-operated-limit-switch) IEEE-library form of cam-operated limit switch: a cam-operated limit switch changes its electrical contact state when a defined cam profile reaches the actuator. ## In plain English ### What does ANSI/IEEE Cam-operated limit switch form mean? This reference locates cam-operated limit switch in Autodesk's IEEE-oriented limit switches family. A cam-operated limit switch changes its electrical contact state when a defined cam profile reaches the operating mechanism. Its position function depends on the documented cam and mechanism relationship. The public library uses HLS11S13 for its horizontal representation; this is a vendor block name, not an IEEE standards symbol number. ### A simple example Read the operating mechanism and the contact reference state together. Cross-reference every associated contact to the same device and show which movement, signal or reset changes its condition; the symbol alone does not establish the complete switching sequence. ### What the drawings help you do Link the cam position to the electrical contact schedule. Cam operation is a mechanical input, not an electrically programmed timer. The linked functional counterpart explains the same operating role in its own drawing context; agreement of every detailed convention mark is not asserted. ### This particular reference IEEE-library form of cam-operated limit switch: a cam-operated limit switch changes its electrical contact state when a defined cam profile reaches the operating mechanism. Cam operation is a mechanical input, not an electrically programmed timer. ### Terms - Normally open / normally closed: The contact state in the normal condition defined for the drawing. - Signal: Electrical information passed between devices, rather than necessarily the main power supply. - Rating: A value stating the conditions for which equipment is specified. Concept diagram: Identify the device and form → Read the connections and state → Check the equipment reference A guide to reading this reference.

Link the cam position to the electrical contact schedule. Cam actuation is a mechanical input, not an electrically programmed timer. The linked functional counterpart explains the same operating role in its own drawing context; agreement of every detailed convention mark is not asserted. ## How to read it - Link the cam position to the electrical contact schedule. - The preview is an original explanation of this function. Match the actual drawing convention to its legend and the selected equipment documentation. ## Information to show or reference - Reference cam detail - Identify operated contact - State normal mechanism position ## Important distinction Cam actuation is a mechanical input, not an electrically programmed timer. ## Facts - Convention evidence: Autodesk IEEE Symbol Preview: Limit Switches; published form: Limit Switch Normally Open - Cam Driven. - Public vendor block: HLS11S13. Vendor library token, not an IEEE symbol number. - Drawing role: Actuated indication - Identifier status: The short label is a functional lookup label, not an assigned IEC or IEEE symbol number. Any separately listed Autodesk code is a verified vendor block name. - Artwork scope: Original educational geometry. Exact standard graphics, product ratings and terminal pinouts are not certified. ## Public references - [Autodesk IEEE Symbol Preview — Limit Switches](https://help.autodesk.com/cloudhelp/2021/ENU/AutoCAD-Electrical/files/GUID-C0135D6B-F4A5-4954-85E0-5B188E5FF5C9.htm) — Autodesk. Public IEEE-oriented Limit Switches table explicitly lists HLS11S13 as Limit Switch Normally Open - Cam Driven.
