Light Steady
The steady signal light is a device providing continuous illumination, used to indicate operational states, alerts, or guidance clearly and consistently. It is widely applied in industrial, commercial, and security environments where continuous visual signalling without flashing is essential.

Audible & Visual Signal Devices and Control Push Buttons
At Henvi, we offer a comprehensive range of human-machine interface (HMI) devices. Our signal devices and control push buttons are essential components for monitoring and controlling industrial processes, ensuring that the status of any operation is communicated clearly and safely to operators.
Signalling Solutions for Safety and Alerts
Effective signalling is the first line of defence against operational errors. Our catalogue includes:
- LED Visual Signal Devices: Signal towers and panel indicators with high visibility and low power consumption.
- Audible Signal Devices: Industrial sirens and buzzers for audible alerts in high-noise environments.
- Combined Devices: Devices that combine light and sound for maximum alert effectiveness.
Control and Emergency Push Buttons
Precise manual control is vital for the safe operation of machinery. We distribute a wide range of:
- Push Buttons: Flush, protruding and illuminated versions in various colours (IEC standard).
- Emergency Stop Buttons: With latching mechanisms and “push-to-stop” action for immediate shutdowns.
- Panel Indicators: With standard mounting holes (e.g. 22mm) for easy integration into electrical panels.
Why Choose Henvi Control Devices?
As a trusted partner in the electrical sector, Henvi ensures that all signal devices and push buttons comply with standards for impact resistance and protection against dust and liquids (IP rating).
Whether for assembling a new automation panel or maintaining a production line, we provide technical support to help you choose the correct rating, colour and function (NO/NC), ensuring that your control system is intuitive and reliable.
Frequently Asked Questions About Signalling and Control
What are the standard colours for industrial control push buttons?
According to international standards, green is used for start, red for stop or emergency, and yellow for interventions or abnormal conditions. At Henvi, you will find all standard colours to ensure full compliance.
What does a 22mm mounting hole diameter mean?
A 22mm diameter is the most common industrial standard for mounting push buttons and signal devices on electrical panel doors or control consoles, allowing easy replacement between different brands.
What is the difference between continuous and intermittent audible signalling?
Continuous signalling is generally used for normal operating states or minor warnings, while intermittent signalling (pulsing) is used to immediately attract attention in situations involving danger or critical failure.
