This PCB DIP Switch is designed for reliable manual programming, configuration, and equipment setting applications. It uses gold-plated contacts with a contact-wiping action to provide low contact resistance and stable electrical performance.

The switch features a tactile operating mechanism with positive contact pressure, an epoxy-sealed base to help prevent flux penetration during wave soldering, and UL 94V-0 flame-retardant plastic construction. It is suitable for electronic equipment where settings need to be configured manually directly on the PCB.

Key Features

Gold-plated contacts provide reliable electrical performance and low contact resistance, while the wiping action during make and break helps maintain a clean and stable contact surface. The tactile mechanism provides positive switching feedback, and the epoxy-sealed base makes the switch suitable for compatible PCB soldering processes.

The flame-retardant housing is manufactured from UL 94V-0 rated plastic, making the switch suitable for use in a wide range of electronic, communication, industrial, and control equipment.

Soldering Conditions

For solderability testing, the specified condition is 230 ±5°C for 5 ±0.5 seconds, with approximately 95% minimum solder coverage.

Resistance to soldering heat is specified at 260 ±5°C for 5 ±1 seconds.

These temperature and time limits should be observed during PCB assembly to prevent damage to the switch.

Applications

This DIP switch is suitable for computer terminal equipment, communication systems, remote controls, burglar alarm systems, vending machines, gaming equipment, industrial controllers, measuring instruments, and embedded electronic devices.

It can be used for manual functions such as device address selection, operating mode configuration, price settings, equipment programming, communication settings, and other PCB-level configuration requirements.

Important Note

The supplied specifications do not identify the exact number of switch positions. The correct position count should be selected according to the specific product variant.

The 100mA rating is a non-switching rating and should not be interpreted as the allowable current while actively switching a load.
