Selection Notes

Push-push (self-lock) operation means one press latches the 1 NO contact closed and a second press releases it, so this variant holds a maintained state without a key or separate twist action - suited to on/off selection rather than momentary commands. The unmarked black flush head keeps it neutral for general-purpose control where no specific IEC 60204-1 colour meaning (start, stop, reset) applies. For a momentary (spring-return) action instead, choose the equivalent XA2EA... monolithic or illuminated XA2AW... variants in the same range.
