Safety button with key 1 NC 2 NO standard SP22-BSN-12. SP22-BSN-12\.

Safety button with key – reliable protection and control

This red safety button with key, with a 22 mm diameter hole, is a solid solution for applications requiring additional protection against unauthorized start-up. It is ideal for control systems, machines and devices where operator safety and protection against accidental activation are a priority. Made of high-quality materials, it ensures long-lasting and trouble-free operation even in harsh industrial conditions.

Construction and application

The SP22-BSN-12 button is characterized by a mushroom-shaped actuator and the ability to lock it with a key. This design minimizes the risk of accidental pressing, which is particularly important in safety-related applications. The IP65 protection class guarantees resistance to dust and water jets, allowing installation in environments exposed to moisture and contamination. Designed for mounting in holes with dimensions of 22 mm x 22 mm.

The button has one normally closed (NC) contact and two normally open (NO) contacts, allowing for flexible configuration of control circuits. Screw connection ensures a secure and durable connection of wires with a cross-section from 0.75 to 2.5 mm². Made of durable plastic, the gray front ring adds aesthetics and protects against mechanical damage.
