Overview
The IDEC AVW401-R is a rugged emergency-stop pushbutton switch designed for industrial control and safety systems. The AVW401-R is a 40mm Emergency-Stop Pushbutton Switch with push lock – turn reset operation. It features a red mushroom button, 1nc contacts, and screw-terminal configuration. It features a chrome plated octagonal locking ring that fastens from the front of the panel. Part of IDEC’s durable TW Series, this switch is built for harsh industrial environments where reliable emergency shutdown is critical.
Key Features

- Applications requiring positive push-lock-turn-reset actuation
Compatibility & Replacements
The AVW401-R is part of IDEC’s modular TW Series platform. These devices feature modular construction for maximum flexibility, and snap on, self‑cleaning contact mechanisms, which allow for a wide current rating. Alternative IDEC emergency-stop models include the AYD311N-R (dual contact version) and AVW411-R (1NO/1NC dual contact model). Omron A22NL and A22NN series switches offer comparable functionality in 22mm footprints. Always verify contact configuration and voltage ratings when substituting emergency-stop switches.
