Push Buttons are one of the most essential control devices used in the electrical panels of Boilers and Heaters. They serve as simple, reliable, and user-friendly manual switching devices for controlling electrical circuits, enabling operators to perform critical operations such as Start, Stop, Reset, Trip, and Emergency Shutdown. Push buttons are mounted on control panels or operator stations and provide direct interface between the operator and the electrical control system.
In Boiler and Heater applications, push buttons ensure safe operation and manual override of automation systems during commissioning, maintenance, or emergency conditions. They are available in illuminated and non-illuminated types, and color-coded as per industry standards (Green for Start, Red for Stop, Yellow/Amber for Fault, Blue/White for specific functions). These push buttons are designed for rugged industrial environments with high electrical endurance, mechanical durability, and resistance to heat, dust, and moisture, making them suitable for continuous operation in boiler houses, process plants, and heater systems.
