Button retainer frames and PIN pad structural components — precise aperture tolerances for smooth button travel, rubber keymat retainer, and PIN pad structural surround. ABS or PC/ABS.
The keypad frame (button retainer or PIN pad frame) holds button caps or a rubber keymat in precise position above the PCB switches. It is typically a separate injection-molded part that clips or screws into the main housing — allowing keypad service or replacement without full terminal disassembly.
Critical design requirements:
Keypad frames are tolerance-critical. A 0.2 mm error in button aperture position causes a button that feels spongy or sticky. We verify button clearances in the CAD before machining prototypes, and hold ±0.1 mm in production tooling.
±0.1–0.15 mm per aperture. Clearance between button cap and aperture wall is 0.1–0.2 mm per side.
It holds the keymat or button caps in position against the PCB switches. Separate from the housing so the keypad can be serviced or replaced without full disassembly.
Yes. Send the reference terminal or keypad section photos and button layout dimensions. We model the frame and confirm aperture positions before manufacturing.
Send button layout and reference photos. We hold ±0.1 mm on all apertures. No CAD needed. Quote in 24 hours.
