Mushroom button Ø40 red 2-position screw-in metal actuator 1NO + 1NC 9001KR9R94H13

Mushroom button – a reliable control element

This screw-in mushroom button with a diameter of 40 mm is a solid and durable solution for industrial and other applications. The red head color provides high visibility, which is crucial in situations requiring a quick response. The metal drive construction guarantees long-lasting and trouble-free operation, even in demanding conditions. The button is designed for mounting in panels and enclosures, and its versatility makes it suitable for use in many devices and machines.

Construction and functionality

The button has two control positions and a contact configuration of 1NO (normally open) + 1NC (normally closed). This means that when the button is pressed, one circuit will be closed (NO) and the other opened (NC). Screw connection ensures a secure and durable connection of the wires. Additionally, the chrome-colored metal front ring not only enhances the aesthetics of the device but also increases its resistance to mechanical damage. The mounting hole diameter is 31 mm.

Durability and protection

The construction of this button is designed for operation in harsh industrial conditions. The IP66 protection class guarantees complete protection against dust and a water jet – making it an ideal choice for outdoor applications or in environments with increased humidity. It also meets the NEMA 13 standard, confirming its resistance to external factors. The lack of backlight does not affect its functionality, and can even be an advantage in applications where an additional light source is undesirable. The button is non-latching – after being pressed, it remains in the active position until pressed again or released by an external control circuit.
