The sensors of the vandal-proof push-buttons are sealed in special resin to ensure extremely high resistance to harsh environmental conditions, vandalism or chemical solvents. The high-quality switches can withstand temperatures of more than -196°C to +2600°C - without losing any of their reliability.
In contrast to mechanical switches, the electronic-capacitive SENSOR switches are completely contactless with several 100 million switching cycles and are therefore extremely durable and maintenance-free.
