The mushroom-head emergency stop halts the machine per ISO 13850 and IEC 60947-5-5: red 22 or 40 mm head on a yellow background, mechanical latching and twist-to-release. It must use an NC contact with positive (direct) opening action, so pressing the head mechanically forces the control circuit open.
The mushroom-head emergency stop is a safety pushbutton used to stop a machine or process when a hazardous or abnormal condition appears. At TECTUL it is quoted by industrial line in 22 mm or 40 mm versions, with mechanical latching and twist-to-release, normally associated with an NC safety contact according to the circuit. Its function differs from a standard industrial pushbutton because it is not used as a frequent operational command, but as a visible, accessible and quick-action device for emergency stopping. In machinery design, ISO 13850 is used as a reference approach for the emergency stop function and IEC 60947-5-5 for electrical devices with mechanical latching; final integration must be validated with the control system, safety relay or logic defined by engineering.

| Requirement | Specification |
|---|---|
| Color | Red head on yellow background |
| Contact | NC with positive opening action (the stem directly drives the contact open) |
| Latching | Latches when pressed; released by twisting or by key |
| Commercial diameters | 22 mm head (standard panel) or 40 mm (higher visibility) |
| Stop category (IEC 60204-1) | 0 = immediate power removal · 1 = controlled stop, then power removal |
The emergency stop function is governed by ISO 13850 and the device by IEC 60947-5-5. Stop category 0 or 1 is defined in the machine's electrical design per IEC 60204-1.
The price depends on diameter, number of contacts and required configuration. TECTUL quotes via WhatsApp according to application and quantity.
The mushroom-head emergency stop is designed for emergencies, with latching and deliberate release. The 22 mm industrial pushbutton is used for normal command orders such as start, operational stop or reset.
In safety circuits an NC contact is commonly used so that an opening activates the stop. The exact configuration must be defined according to the electrical design and risk assessment.
The lot allows quoting a 22 mm or 40 mm mushroom-head emergency stop, according to the pushbutton station or panel where it will be installed.
It is mounted on a panel or pushbutton station, the actuator is fixed, the contacts are connected to the safety or control circuit and the stop is tested with authorized personnel.
Indicate diameter, quantity, required contacts, control-circuit voltage, machine type and whether it will be installed in a panel or pushbutton station.
Category 0 removes power immediately and applies when a coast-to-stop is safe; category 1 brakes the machine in a controlled way and then removes power, needed for loads with dangerous inertia. IEC 60204-1 defines it in the machine design.
No. The e-stop halts a running machine but does not guarantee de-energization for maintenance: working on the equipment additionally requires disconnection with visible break and padlock lockout.
