Siemens 52PR8W2A Pushbutton

Siemens 52PR8W2A Pushbutton is a 30 mm two-position pushbutton operator with twist-to-release action and a red mushroom-style actuator, designed for rugged industrial control panels. It provides 1 normally open and 1 normally closed contact configuration, enabling straightforward start/stop or interlock applications. The unit is part of the Siemens 52 pushbutton family, featuring a 1 3/4 inch (about 44 mm) mushroom head and a compact 30 mm body footprint. Electrical ratings include up to 60 A AC and up to 110 V AC, making it suitable for heavy-duty control circuits in machinery and panels. The two-position twist-to-release mechanism delivers a maintained action that stays in place until released by twisting, a common choice for safety interlocks and primary control sequencing in industrial environments. Typical applications encompass control panels, machine start/stop control, and interlocks in industrial automation setups, where a robust, clearly identifiable red actuator helps operators quickly locate the control.
