Product Overview
The Car Power Switch Base is the structural carrier inside an automotive power switch. It locates the moving switch parts and circuit board, then connects the switch mechanism to the dashboard, console, or electrical control assembly through its mounting features.
Core Advantages
±0.05 mm Interface Control
Critical dimensions are controlled to ±0.05 mm. Accurate locating features prevent side play and misalignment after the button, spring, contact mechanism, and circuit board are assembled on the base. This helps avoid an uneven press or intermittent response.
PC Heat Resistance up to 120°C
PC is available for switch bases installed beside powered electrical components and is specified for continuous heat resistance up to 120°C. The base retains its PCB reference points and mounting geometry as the switch area warms up.
PA6 for Structural Clips and Supports
PA6 is available for bases with load-bearing clips, posts, and retaining features. It supports the internal mechanism during repeated button operation and assembly loading, reducing the need for a metal carrier at every structural point.

Customization Capabilities
Base Geometry and PCB Interface
The project may cover the outer dimensions, PCB posts, terminal openings, button guides, spring seats, snap joints, screw bosses, connector clearance, and panel-mounting features.
Material and Structural Details
PC or PA6 may be selected according to the specified thermal and mechanical requirements. Wall thickness, ribs, local reinforcement, clip geometry, and gate location may be adjusted to control stiffness and warpage.
Variant Development
Different switch layouts, colors, terminal arrangements, and mounting interfaces can be produced from drawings or samples. Multiple confirmed models can share a common design platform where the internal interfaces allow it.
Quality Control
Dimensional Verification
Vision systems and dedicated gauges check the ±0.05 mm controlled locations, including PCB supports, button guides, terminal slots, and mounting points. First-piece approval establishes the cavity and process reference.
Flatness, Warpage, and Clip Inspection
The base is checked on a fixture for flatness and assembly seating. Snap joints, screw bosses, and clips are inspected for incomplete filling, stress whitening, cracking, and retention after assembly.
Production Monitoring
Patrol checks cover material identity, molding condition, cavity consistency, and surface defects. Key dimensions receive final inspection before the batch is released for packing.
FAQ
Q1: What is the MOQ for a Car Power Switch Base?
A1: The MOQ is 10,000 pieces. Confirmed colors or models may be combined within the order.
Q2: What payment term is available?
A2: The payment term is 100% prepayment.
Q3: Is the product supplied with contacts, terminals, or a PCB?
A3: The standard scope is the molded switch base. Contacts, terminals, PCB parts, or subassembly work are included only when they appear in the confirmed bill of materials.
Q4: Can parts from different mold cavities be identified separately?
A4: Yes. Cavity marks and packing identification may be retained when the project requires cavity-level comparison or production traceability.
