XB2-EG21 Key Selector Switch 22mm 2 Positions 1 Normally Open Contact
The XB2-EG21 is a key-operated rotary selector switch designed for panel mounting in electrical control circuits. Featuring a 22mm standard mounting diameter, it fits seamlessly into standard industrial control panels and pushbutton stations.
The switch operates in 2 positions and is equipped with 1 normally open (NO) contact, making it ideal for simple ON/OFF or enable/disable control functions.
The key-operated mechanism ensures that only authorized personnel holding the correct key can operate the equipment — an essential security feature for machine control, power circuits, and process equipment. Two identical metal keys are supplied with each unit, allowing operation by multiple authorized users.
Finished in durable black, the switch head is compact, robust, and built for daily industrial use.
