What the Keypad Frame Does
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:
- Button aperture tolerance — ±0.1–0.15 mm clearance per side; too tight and buttons stick, too loose and buttons rattle
- Keymat seat — if using a rubber keymat, the frame must retain the keymat precisely so all actuators align with the PCB switches below
- Switch pre-travel — the frame controls the vertical position of the keymat or button cap relative to the PCB switch actuation point
- Mounting interface — clip hooks or screw bosses that hold the frame against the main housing without flex under button presses
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.
