Safety button with key – reliable installation protection

This red safety button with key, designated SP22-BSN-15, is a control element designed for applications requiring enhanced security and access control. It is ideal for systems where it is necessary to prevent accidental starting or stopping of a device. The key lock provides an additional layer of protection against unauthorized use.

Construction and application

This button combines the function of a standard control button with a key lock mechanism. Thanks to this, in addition to standard control, it is possible to physically prevent the device from being turned on or off without the appropriate key. This solution is used in industrial machines and equipment, alarm systems, and anywhere else where additional protection against unauthorized access is required. The button has two current paths – normally closed and normally open – which increases its versatility. The ability to illuminate it further improves its visibility in difficult lighting conditions.

Features and benefits

• Durable construction: The button housing is made of high-quality materials, which guarantees its durability and resistance to mechanical damage.
