Practical Unionwell engineering guidance on Unionwell Participating The 9th Shanghai International New Energy Auto Technology And Supply Chain Expo for EV Charging. Define the sensed position, mechanism movement, circuit, and environment, then confirm product ratings and validation requirements with Unionwell.
Use this page as an on-site starting point, not as a substitute for a controlled drawing or model-specific datasheet. Final selection depends on the actual switch position, movement, circuit, operating environment, and validation plan.
Typical operating points to review
Charging-gun release and lock
Detect button or lock movement and provide a position input to the charging control sequence.
Discuss this positionVehicle inlet locking pin
Confirm the position of a compact locking mechanism during connection and release.
Discuss this positionPort cover and access door
Report whether an access cover or service door has reached its intended position.
Discuss this positionCharging-pile cabinet access
Provide a door-state input for equipment access monitoring and control interlocks.
Discuss this positionThese are application examples for project discussion. Confirm the exact configuration, ratings, approvals, and system-level suitability with Unionwell engineering.
Four checks before you shortlist a switch
- Define the signal. Identify the position or event the mechanism must detect, including normal, released, and fault states.
- Map the movement. Share actuator type, available travel, operating force, mounting envelope, terminal direction, and tolerance stack.
- Specify the conditions. State voltage, current and load type, switching frequency, temperature, moisture, dust, vibration, and expected operating life.
- Plan validation and supply. Include required approvals, sample and test expectations, annual volume, project stage, target timing, and drawing revision.
Send a drawing, mechanism photo, or incumbent part number with your RFQ when available. The team can then check the mechanical interface and electrical requirements together.
