Mushroom control button – reliability and safety in every circuit

This black mushroom button with a nickel-plated ring is a solid element for building control panels, control cabinets, and enclosures for machines and devices. Designed for mounting in 22 mm diameter holes, it provides convenient and safe operation of electrical devices. The construction of this button allows for switching circuits with a current of up to 2.5 A, as well as light and sound signaling.

Construction and application

The button is characterized by self-return, which means that after release it returns to its initial position. Two normally closed contacts allow you to control various functions in the installation. The front ring made of high-quality plastic in gray color provides an aesthetic appearance and additional protection against mechanical damage. The round shape of the lens and high resistance to external factors (IP65) guarantee reliable operation even in harsh industrial conditions.
