Protruding red button 1 NC 1 NO nickel-plated ring ST22-WC-11. ST22-WC-11\.

Control button for panels – reliability and safety

This protruding red button, designed for mounting in 22 mm diameter holes, is a solid electrical accessory. It will work well in both industrial applications and control devices. The construction with a nickel-plated ring ensures an aesthetic appearance and corrosion resistance. This button is particularly useful where quick and clear signaling or immediate shutdown of the device is required.

Functionality and technical parameters

The button has one normally open (1NO) and one normally closed (1NC) contact, making it a versatile solution for various control circuits. Its high resistance to external factors, confirmed by the IP65 protection class, guarantees reliable operation even in difficult environmental conditions – dust and moisture are not a problem. Made of durable materials, including a plastic front ring, it ensures long-term operation. Non-latching means the button remains pressed until released – ideal for safety functions or interlocks.

Installation and application

Button installation is simple thanks to the screw connection. It finds wide application in:

• Control cabinets: as an element of operator panels and control systems.
• Machines and equipment: for starting, stopping or resetting processes.
• Emergency applications: as a STOP button (mushroom type) providing quick shutdown of the device in hazardous situations.
• Industrial equipment: where reliability and resistance to mechanical damage are required.
• Building automation: as an element of systems controlling lighting, heating or ventilation.

Thanks to its compact dimensions (22 mm hole diameter) it can be easily integrated with existing installations. Additionally, the round shape of the lens provides good visibility even at an angle.
