The AVN3B-R is a red pushbutton operator designed for ø40mm pushlock turn-reset stop switches in the TWTD Series. This component is part of IDEC's rugged, heavy-duty industrial control lineup and features a non-illuminated design with 1NO (one normally open) contact arrangement. The button is constructed with durable materials consistent with the TWTD Series' chrome-plated zinc locking ring and die-cast zinc mounting threads, ensuring reliable performance in harsh industrial environments. It is compatible with the modular TWTD architecture, allowing integration with various contact blocks and mounting configurations. The AVN3B-R is commonly used in emergency stop circuits, machine control panels, and industrial automation systems where a dedicated red stop button is required for safety compliance and operator recognition.
