Red mushroom button 1 NC 1 NO, nickel-plated ring SP22-DC-11. SP22-DC-11\.

Control button – reliability and safety in every circuit

This red mushroom button SP22-DC-11 from Spamel is an element designed for control and signaling in electrical circuits. It finds application in machine control panels, switchboards and other industrial installations, as well as in applications requiring emergency shutdown. Its solid construction and high degree of protection (IP65) guarantee reliable operation even in harsh environmental conditions.

Construction and functionality

The button is characterized by a self-resetting design, which means that after release it returns to its initial position. It has one normally open (NO) and one normally closed (NC) contact, which allows its use in various circuit configurations. Mounting is done in a 22 mm diameter hole, and the electrical connection is made using screw connections. The front ring made of plastic provides additional protection and an aesthetic appearance. The red color of the mushroom makes the button easily recognizable, especially in emergency situations.

Application and benefits

The SP22-DC-11 button is an ideal solution for installers and users looking for a reliable control element. Its versatility allows it to be used in a wide range of applications:

• Industry: Machine and device control, safety systems.
• Automation: Switching circuits on/off, signaling operating states.
• Construction: Alarm systems, access control.
• Emergency shutdowns: Quick power cut-off in hazardous situations.

Thanks to compliance with PN-EN 60947-5-1 and IEC 60947-5-1 standards, the button meets stringent safety requirements. Made of high-quality materials, it ensures long-lasting and trouble-free operation. Additionally, the compact dimensions facilitate installation even in tight spaces. The IP65 degree of protection guarantees resistance to dust and moisture, which is particularly important in harsh industrial conditions.
