When selecting a switch assembly machine, you must prioritize Production Capacity (PPH - Pieces Per Hour), typically ranging from 1,200 to 3,600 PPH depending on complexity. Ensure the machine supports High-Precision Indexing Drives for accurate positioning and features PLC Control Systems (e.g., Siemens or Mitsubishi) for stable operation. Additionally, verify the Compatibility with different switch types (rocker, toggle, or micro-switches) and the availability of CCD Visual Inspection Systems to detect assembly defects in real-time.
