IDEC YW1B-V4E01R Emergency Stop Switch, SPST-NC, 120V 10A, 40mm

The IDEC YW1B-V4E01R is a highly reliable SPST-NC (Single Pole, Single Throw, Normally Closed) emergency stop push button switch, designed for critical safety applications in industrial and commercial settings. Its prominent 40mm diameter red mushroom-style head ensures immediate visibility and can be activated quickly and easily under pressure, even with gloves.

This robust switch features a pull-and-turn reset mechanism, which prevents accidental reactivation and ensures the machine remains safely de-energised until deliberately restarted. The switch is housed in a durable enclosure that provides an IP65 ingress protection rating, making it dust-tight and protected against low-pressure water jets from any direction.

Key Features & Applications

• High Visibility Safety: The large red mushroom head is a universally recognised symbol for emergency stop functions, facilitating rapid operator response.
• Secure Reset: The pull/turn-to-reset operation guarantees intentional reactivation, enhancing operational safety protocols.
• Robust Construction: Built for harsh industrial environments with an IP65 rating for resistance to dust and water.
• Simple Installation: Features screw terminals for secure and reliable wiring connections, and is designed for a standard 22mm panel mounting hole.

With a maximum contact rating of 10A at 120V AC, this switch is suitable for controlling a wide range of industrial machinery, control panels, conveyor systems, and automated equipment where operator safety is paramount.
