One tiny press can start a production line, stop a machine in an emergency or wake up a whole control panel, so a push button switch has to be ready every single time. Built by Essen Deinki, these modular switches shrug off shock and vibration, carry a finger-safe shield and come in six colours, from calm white to alert red. Each push button connection is quick to install and made to IEC/EN 60947-5-1 standards, so panels stay neat, safe and dependable.
