Safety button – reliability and protection in every circuit

This red safety button with a nickel-plated ring, designated SP22-B-22, is a key element ensuring safety and control in electrical installations. Designed for mounting in 22 mm diameter holes, it is perfect for both industrial applications and home installations requiring immediate circuit disconnection. The non-latching design guarantees maintaining the off state until manually returned to the initial position – which is particularly important in emergency situations.

Construction and application

The SP22-B-22 button is characterized by a solid construction and high resistance to environmental conditions (IP65 protection class). Made of durable materials, it ensures long-lasting and trouble-free operation. Thanks to two normally open and two normally closed contacts, it enables effective control of circuits with a current of up to 2.5 A. It is ideally suited for applications requiring quick and reliable power disconnection, e.g. in machines and production equipment, control cabinets or alarm systems. The gray front ring made of plastic adds aesthetics and facilitates integration with various control panels.
