Environments where high-pressure cleaning or dust exposure is common
This switch may not be suitable for applications requiring momentary-contact operation, as this specific model features a latching mechanism. Additionally, it is not intended for use in environments where the specific RONIS lock number 455 is not compatible with existing security protocols.
