MP1-10B is a non-illuminated momentary flush pushbutton operator in ABB's 22mm modular pilot device range. The device features a black plastic button with a flush design and momentary contact action, allowing it to return to its normal state when released. It is part of a modular system that supports snap-on installation for reduced setup time and includes a rear-mounted contact block holder with quick-release locking mechanism for secure assembly. The MP1-10B is commonly used in industrial control panels, machinery interfaces, and automation systems where reliable momentary switching is required without illumination.
