The main characteristics of the four corner metal dome
Structural features: The cross shaped pot piece has four legs, also known as four corner spring pieces or pot pieces. This structure makes it perform well in membrane switches and control panels, with good hand feel, high stroke, and long lifespan (up to 1 million cycles).
Application scenarios: Cross shaped pot pieces are widely used in thin film switches, control panels, single-sided, double-sided, and multi-layer hard boards (PCBs), flexible circuit boards (FPCs), and various controllers. They are particularly suitable for PCB designs that require large space, such as membrane switches and panels.
Size range: Common sizes of cross shaped pot pieces include 6mm, 7mm, 8.4mm, 10mm, 12.2mm, 16mm, and 20mm. The selection of these sizes depends on the space size and design requirements on the PCB.
Mechanical properties: The force range of the cross shaped pot piece is generally between 120 grams and 600 grams, with high operating force and rebound force, suitable for application scenarios that require large operating force.
Customized service: According to customer needs, cross shaped pot pieces of different specifications, sizes, and strokes can be customized, even with feet or hollow designs, to meet specific application requirements.
Four corner metal dome application
Large space equipment
Due to its large size (commonly 6-20mm in diameter), it is suitable for film switches, control panels, and medical instrument buttons with ample PCB space.
Typical use cases: Building intercom systems, access control equipment, electric toothbrushes, massage instruments, and other products that require high touch feedback.
High frequency industrial scenarios
Cross reinforcement structure optimizes rebound speed (response time<10ms for some high-end applications), suitable for high-frequency operating environments such as production line control panels and automotive ignition systems.
Flexible line adaptation
Widely used for single/double-sided hard boards (PCBs) and flexible circuit boards (FPCs), it can be assembled into conductive film components by bonding PET substrates to simplify assembly.
Our production capacity
It has 12 automated production lines, with a daily production capacity of 5 million pieces, supporting large-scale order delivery, and can also undertake small batch customized orders (such as special size, heterogeneous structure).
