Frequently asked questions & answers
Is this item easy to use?
Yes, it is. There is also a short demonstration video available.
What are the dimensions of this item?
68 x 68 x 53 mm
What is the different between a push button switch for an emergency stop and a general-purpose push button switch?
A general-purpose push button switch is used for controls, e.g. to start machine operation or simply to switch modes. An emergency stop push button switch however, is mainly used as a safety measure to stop hazardous events.
What type of environments can this push button operate in?
This push button is designed to function effectively in harsh environments, with an operational temperature range of -40°C to 70°C and a high-pressure resistance to water ingress characterised by IP66, IP67, and IP69K ratings.
How does the twist release mechanism enhance safety?
The twist release feature prevents accidental activation, ensuring that only intentional actions lead to equipment shutdown. This design increases workplace safety by minimising the risk of unintended stops during operations.
What is the significance of the 2NC contact configuration?
The 2NC configuration ensures a reliable breakdown of the circuit when activated, enhancing safety by cutting off all power to machinery, thereby preventing potential hazards during an emergency.
Can this push button be used in outdoor applications?
Yes, it is suitable for outdoor applications due to its excellent IP ratings, protecting against moisture and dust ingress while ensuring consistent performance in varying weather conditions.
How can I install the push button in my control panel?
Installation requires a simple surface mounting process with one knock-out for cable entry, accommodating various cable sizes. It is designed for straightforward integration with existing control and signalling systems.
