IDEC YW1B-V4E02R Emergency Stop Push Button, DPST-NC, 120V AC

The IDEC YW1B-V4E02R Emergency Stop Push Button Switch is a crucial safety component designed for reliable, fail-safe operation in industrial control panels and machinery. Featuring a prominent 40mm diameter red mushroom-style actuator, it provides clear visual identification and immediate, intuitive access in critical situations. The switch utilises a pull and turn to reset mechanism, preventing accidental or unauthorised reactivation and ensuring the machine remains safely stopped until the underlying issue is resolved and the operator deliberately resets the system.

Constructed to meet an IP65 protection level, this switch is dust-tight and protected against low-pressure water jets from any direction, making it suitable for use in harsh industrial environments where contaminants or washdowns are a concern. Its robust build and 22mm panel mounting hole requirement offer secure installation. Electrical connection is facilitated via reliable screw terminals.

Key Electrical Specifications

The switch is configured as Double Pole Single Throw, Normally Closed (DPST-NC), providing two independent circuit-breaking paths for enhanced safety and redundancy. It is rated for a maximum contact current of 10 Amps and a nominal AC voltage of 120V, making it compatible with standard industrial control circuits. This emergency stop is part of IDEC's trusted YW1B-V4E0xR series, known for its durability and compliance with international safety standards.

Applications & Use

Essential for any safety-conscious workshop or production line, this push button is engineered for integration into machinery, conveyor systems, control panels, and automated equipment where a positive, latching emergency stop function is required by law and best practice. Its design prioritises operator safety and equipment protection.
