Core Definitions & Terminology Included

1. Changeover Switch: General term for this universal rotary transfer switch, used to switch between multiple power supply loops, control circuits and measurement circuits.
2. cam switch: Its core working principle relies on precision cam drive structure to control contact on/off sequence, realizing accurate multi-position circuit conversion.
3. 16A Changeover Switch: Rated conventional heating current: 16A, suitable for low-capacity AC/DC circuit switching scenarios.
4. key lock changeover switch: Equipped with cylinder key locking device; the key can only be inserted and pulled out at designated gear positions, preventing unauthorized misoperation and accidental circuit switching.

    

   Key Features

   ✅ Blank No-Logo Panel Design

    

   Front faceplate without factory fixed logo/characters, flexible for custom text, gear symbols and parameter marking, ideal for equipment brand matching.
   ✅ Secure Key Lock Mechanism

    

   Typical key lock changeover switch structure; keys are removable only at locked positions. It effectively avoids accidental rotation by irrelevant personnel, greatly improving electrical operation safety for power distribution cabinets, machine tools and automation equipment.
   ✅ Durable Cam Switch Core

    

   High-precision cam positioning system ensures crisp switching feel, consistent contact pressure and long mechanical service life; anti-arc silver alloy contacts resist ablation for stable conductive performance.
   ✅ Standard 16A Rated Current

    

   Classified as standard 16A Changeover Switch, applicable to AC 50/60Hz up to 380V, DC 220V and below low-voltage control loops.
   ✅ Compact Single-Hole Installation

    

   Ø22mm standard panel mounting hole, easy to install on control cabinets, CNC machine tools, engineering machinery, elevator and power equipment panels; front protection grade reaches IP65 for dustproof & waterproof indoor/outdoor industrial use.
   ✅ Wide Application Scenarios

    

   Widely used for circuit conversion, voltage/current signal selection, small motor forward/reverse control, power switching and program selection on CNC machine tools, automation production lines, power distribution systems, construction machinery and new energy equipment.
