Its non-slip surface enhances usability by reducing accidental presses, even in low-light conditions. Silicone is also resistant to temperature extremes, UV exposure, and moisture, making it ideal for both indoor and outdoor applications. This material contributes to a quiet, responsive pressing experience that users find intuitive and comfortable.

Printed Circuit Board (PCB)

The Printed Circuit Board (PCB) serves as the electronic backbone of the remote control. It is typically constructed from a fiberglass-reinforced epoxy substrate (FR-4), known for its mechanical strength and excellent insulating properties.

Thin layers of copper are etched into precise conductive pathways to connect microcontrollers, resistors, capacitors, oscillators, and RF modules. In 315/433MHz learning remotes, the PCB is designed to support frequency-specific tuning and memory storage for learned codes, enabling compatibility with various garage doors, gates, and security systems.

Infrared & RF Emitters

While many learning remotes operate via radio frequency (RF) at 315MHz or 433MHz, some models also include infrared (IR) emitters for multi-device compatibility. RF emitters use semiconductor materials like gallium arsenide (GaAs) or silicon-based RF chips to transmit encoded signals over longer distances, even through walls.

These emitters are integrated into the PCB and modulated to send unique identification codes. The use of stable semiconductor materials ensures consistent signal output and minimal interference, allowing reliable communication with receivers in gate systems, alarms, and home automation devices.

Metal Components

Internal metal elements—such as connectors, antenna traces, spring contacts, and shielding layers—are typically made from copper, nickel, or tin-plated alloys. These metals are selected for their superior electrical conductivity, ensuring efficient power transfer from the battery to the circuitry.

Copper traces on the PCB facilitate signal routing, while metal springs maintain consistent contact with batteries. Some remotes include a metal RF antenna or conductive ink traces to enhance transmission range and stability. These components also contribute to structural rigidity and help dissipate heat generated during operation.

Rubber Dome Switches

Beneath the silicone keypad lie rubber dome switches—small, inverted domes made of conductive silicone or metalized rubber. When a button is pressed, the dome collapses, making contact with the underlying PCB contacts and completing the circuit.

This mechanism provides tactile feedback (a soft "click") and ensures reliable activation with minimal force. Rubber dome switches are economical, durable, and resistant to dust and moisture ingress, making them ideal for consumer electronics. Their design supports millions of actuations, contributing to the remote’s long service life.
