Protruding red button 2 NC 1 NO nickel-plated ring ST22-WC-21. ST22-WC-21\.

Control button – reliability and durability in every circuit

This protruding red button, with a diameter of 22 mm, is a solid control element designed for applications requiring high reliability. Made of high-quality materials, it ensures long-lasting and trouble-free operation in various industrial and commercial conditions. The construction with a nickel-plated ring adds to its aesthetic appearance and protects against mechanical damage.

Construction and application

The SP22 button is characterized by a high degree of protection IP65, which guarantees resistance to dust and water ingress. Thanks to this, it can be used in both dry and humid environments. Screw connection ensures a secure and stable electrical connection. The button has two normally closed (NC) contacts and one normally open (NO) contact, allowing its use in various control applications. Non-latching means that after pressing the button, it remains pressed until released again – an ideal solution where certainty of maintaining the state is needed.
