Emergency Stop Push Button 22 mm
The Siemens emergency stop push button is a 22 mm maintained-action safety switch designed for industrial machinery and control panels. It provides a single operator with a 40 mm mushroom head for immediate equipment shutdown in hazardous situations. The unit carries a red plastic head and metal bezel for high visibility and durability in demanding environments.
IP67 IP69K Environmental Protection
The IP67 and IP69K ratings mean the switch withstands temporary immersion and high-pressure, high-temperature wash-down cycles common in food processing and heavy industry. NEMA ratings 1, 2, 3, 3R, 4 and 4X confirm resistance to dust, water ingress and corrosion. This protection ensures reliable contact operation where lesser-rated devices would fail.
1NO/1NC Screw Terminal Wiring
Installation uses standard screw terminals for the 1NO/1NC contact block rated at 10 A / 600 V AC and 1 A / 600 V DC. The maintained-action mechanism requires a deliberate twist or pull to reset, preventing accidental restart. Miswiring the normally-open or normally-closed contacts is the most common error, so verify the circuit diagram before commissioning.

Questions about this item
How often should the 1NO/1NC contacts be inspected or replaced on this 22 mm emergency stop button?
The contacts are rated for 10 A at 600 V AC and 1 A at 600 V DC with NEMA A600/R300 designation; inspect them during scheduled safety-system checks and replace if wear or corrosion appears.
What is the first limit reached when the mushroom head is held in the maintained position for long periods?
The 40 mm plastic mushroom head stays mechanically latched until manually reset; the electrical limit is the 10 A AC contact rating, which must not be exceeded during sustained activation.
Does the metal bezel or IP67/IP69K sealing cause noticeable heat or noise when the button is engaged all day?
The screw-terminal switch has no moving parts that generate noise, and the sealed IP67/IP69K enclosure does not produce measurable heat during continuous maintained operation.
