Nidec Copal S-1000A/2000A Rotary Coded Switch

In the field of electronic instrumentation, accurate parameter setting is essential for system reliability. The S-1000A and S-2000A series provide a robust solution through a precision rotary coded mechanism. This switch allows users to toggle through 10 or 16 positions with distinct tactile feedback, translating mechanical rotation into stable binary or hexadecimal outputs. The internal contact structure is engineered to maintain high contact pressure, protecting signal integrity against mechanical micro-vibrations.

The Nidec Copal S-1000A and S-2000A series are high-precision, surface-mount rotary coded switches. These are essentially “logic switches” used to set addresses or configurations on a circuit board by turning a small rotor to a specific number or letter.

A standout advantage of the Nidec Copal S-1000A/2000A Rotary Coded Switch is its superior process compatibility. Each unit is housed in high-performance, heat-resistant PPS resin, allowing it to withstand the thermal stress of wave soldering without losing structural or mechanical precision. The washable architecture is a critical feature for high-yield manufacturing, enabling the thorough removal of flux residues to prevent long-term signal degradation. Whether you require a top-setting or side-setting orientation, these switches deliver consistent, professional-grade performance in a miniature footprint.
