Siemens 3SU1 Series Push Button Switch, 22.3mm Cutout Diameter, Round 29.45mm Diameter - 3SU1158-3AB42-1MA0
This push-button switch is an illuminated twin control intended for industrial control panels and machine interfaces, providing momentary actuation for signal and safety circuits. It combines a metal high-gloss front ring with plastic actuators in red and green, an integrated LED light source rated for 230V AC, and a front-mount design that delivers sealed operation for demanding environments.
Features & Benefits

What supply voltage does the illumination require?
The built-in LED module is designed for AC supply at 230V and operates at both 50Hz to 60Hz.
How are conductors prepared for the terminals?
Terminals accept solid and finely stranded conductors with and without end ferrules within 0.5 to 1.5 mm² ranges and permit two conductors per connection where specified.
How does the device cope with mechanical stress?
It withstands sinusoidal shock of 15g/11ms and vibration from 10 to 500 Hz at 5g for robust performance in mobile or vibrating installations.
What protective class applies to the terminals versus the front?
The front-mounted assembly attains high ingress protection levels while the Terminal area is rated at IP20 to maintain access safety.
