The IDEC XW1E-BV411M-R is a 22mm emergency stop switch designed with a unique 'safe break action' concept. This innovative design ensures that the normally closed (NC) contacts reliably open even if the switch is damaged or subjected to excessive force, preventing catastrophic events and personal injury. The switch is secured from the rear of the panel, preventing unauthorized removal, and offers both push-pull and push-turn reset options for operator convenience. Its compact size and robust construction make it ideal for use in automated machinery and industrial environments requiring a high level of safety.
