Universal control button for various applications

This red mushroom button, designated SP22-DC-22, is a reliable control element designed for both professional and end-user applications. Its robust construction and high resistance to external conditions make it an ideal choice for control panels, machines and devices. A 22 mm mounting hole diameter ensures compatibility with a wide range of enclosures and panels.

Construction and operating parameters

Buttons from the SP22 series are characterized by high quality and durability. This model has two normally open (NO) and two normally closed (NC) contacts, allowing for the implementation of various control functions. The self-resetting mechanism ensures ease of use - after release, the button automatically returns to its initial position. The IP65 protection class guarantees resistance to dust and water jets, which is particularly important in harsh industrial conditions. The front ring made of gray plastic adds aesthetics and protects against accidental damage. Electrical connection is made using reliable screw terminals.
