Product Information
Full details
This Schneider Electric XB4BG61 key switch is designed for industrial control panels and machinery requiring secure, manual operation. Its key advantage is robust IP66, IP67, IP69(IP69K) protection and a wide operating temperature range, making it suitable for harsh environments. A caveat is its fixed 90-degree angle of throw, which may not suit all control configurations. This 22mm round key switch features a Ronis 455 keylock, a spring return operation, and screw terminals for straightforward integration. It offers a single Normally Open (NO) contact and a durable metal front ring with a chrome finish.

FAQs
What type of key does this switch use?
This switch uses a Ronis 455 key. The key is typically sold separately.
How many electrical contacts does the XB4BG61 have?
The XB4BG61 model has one Normally Open (NO) contact.
What does the IP69K rating signify?
The IP69K rating indicates the highest level of protection against dust and high-pressure, high-temperature water jets, making it suitable for environments requiring frequent, intensive cleaning.
Can this switch be used for continuous ON operation, or does it require the key to be held?
This switch features a spring return operation. When the key is turned to activate the circuit, it will maintain the connection as long as the key is in that position. Removing the key or letting it return to its default position (spring return) will break the circuit. It does not latch in position without the key present.
What is the material of the front ring?
The front ring is made of metal with a chrome finish, providing durability and resistance to corrosion.
What is the mechanical lifespan of this switch?
The mechanical life of the Schneider Electric XB4BG61 key switch is rated for 1,000,000 cycles.
Is this switch suitable for outdoor use?
Yes, with its IP66, IP67, and IP69K ratings and wide operating temperature range, it is well-suited for many outdoor applications.
Troubleshooting
Switch does not activate when key is turned.
Ensure the correct Ronis 455 key is fully inserted. Verify that the wiring is correctly connected to the NO contact terminals. Check that the operating temperature is within the -40°C to +70°C range.
Key is difficult to insert or turn.
Check for debris inside the keyhole. Ensure the key is properly aligned with the lock mechanism. Avoid forcing the key; if resistance is met, remove and re-attempt alignment.
Electrical contact is intermittent.
Ensure wiring terminals are clean and tightened securely. The silver alloy contacts are durable but can be affected by heavy contamination; professional cleaning or replacement might be needed if severe.
Switch body is loose after installation.
Re-tighten the mounting nut from behind the panel. Ensure the front bezel is correctly seated before tightening.
