Switch Enclosures Selection Guide: Technical Criteria & Application Standards
Switch Enclosures selection guide: technical parameters, mounting and compliance standards, and Metop comparison.
A switch enclosure is a plastic housing that encloses a cam switch's body and terminals and allows the switch to be surface-mounted outside a panel. It is preferred where a cam switch is to be used in a closed housing on a machine, on a workshop wall or at points without a panel, and for replacing a broken box. In this category, Metop plastic enclosures are divided by on-off, reversing/pole-changing and star-delta switch types; the product names state switch currents such as 16 A, 25 A, 40 A, 63 A and 100 A. Choose the enclosure according to the function type and current rating of the switch to be installed; if you will use it with a different brand or series, compare the housing dimensions with the manufacturer's data. A switch enclosure must not be confused with an enclosed switch: an enclosed switch is a switch sold with its box fitted, while the items in this category are, according to the product name, the enclosure only. The Switch Enclosures category on Welibaba includes 29 active models from leading manufacturers such as Metop.
Key Technical Parameters for Selecting Switch Enclosures
To specify the right Switch Enclosures model for your panel or installation, verify the following parameters against your engineering schedule:
| Parameter | Typical Catalog Values | Verification Note |
|---|---|---|
| Current | 10 A, 100 A, 16 A, 20 A | Verify against project schedule and load calculation |
| Depth | 56 mm, 64.9 mm, 79.5 mm, 96.5 mm | Verify against project schedule and load calculation |
| Width | 63.5 mm, 76.7 mm, 94.5 mm | Verify against project schedule and load calculation |
| Housing Cable Entry Size | Ø17.5 mm, Ø19 mm, Ø29 mm, Ø23 mm | Verify against project schedule and load calculation |
Installation, Compatibility, and Commissioning Checklist
- Electrical & Mechanical Matching: Confirm that rated voltage, current capacity, and mounting dimensions align with the upstream and downstream components in Cam Switch Accessories and Spare Parts.
- Environmental & Enclosure Rating: Check IP protection class, housing material, and terminal capacity for dusty, humid, or high-vibration industrial environments.
- Related Product Groups: If your application calls for a different form factor or rating, compare sibling categories such as Cam Switch Accessories and Spare Parts.
