Illuminated Pushbutton Switches and Indicators, which are widely usedin power installations, e.g. thermal, hydro and nuclear power plants,
are important components to inform operators of the operational statusof equipment and to assist in safe and efficient management.
Thermal power plants
In boiler and turbine control panels, they are used to indicate
conditions such as temperature and pressure.
Hydroelectric power plants
In generator and gate opening and closing controls, they informthe operator of water level and flow conditions.
Nuclear power plants
In controlling nuclear reactions and monitoring cooling systems, they play
an important role in indicating system status and safety warnings.

Illuminated Pushbutton Switches and Indicators are essential components
to enhance operability and safety of medical equipment.

Medical Industry

Computer Tomography (CT) & other testing equipment
Highly visible illuminated switches and indicators are crucial for accurately
informing operators about the status of the equipment and the ongoing process.
Information from them enables operators to assess the status ofthe equipment and take appropriate action if necessary.
Example of use of indicators in blood analyzers
The green indicator light illuminates during analysis of the blood sample and changes
to blue when analysis is complete. The red indicator light may flash if an error occurs.
