Control button for industrial and fire applications

This red, protruding SP22-WC-11 button, with a nickel-plated ring, is a reliable control element designed for mounting in 22 mm diameter holes. It is suitable for both industrial installations and fire protection systems, where high resistance to external conditions is required. The construction with a key-lockable housing (fire version) provides additional safety and protection against unauthorized use.

Construction and application

The button is characterized by a solid construction and a high degree of protection IP65, which guarantees its trouble-free operation even in difficult conditions - dusty or humid. Its versatility results from the possibility of use in various electrical circuits, thanks to the combination of one normally open (NO) and one normally closed (NC) contact. Screw connection ensures a secure and durable connection of wires with a cross-section from 1 to 2.5 mm².

The SP22 button is compatible with PN-EN 60947-5-1 and IEC 60947-5-1 standards, which confirms its compliance with European safety standards. Therefore, it can be used without fear in various industrial applications and alarm systems. The housing with protection class II provides additional safety for users.
