A pressure switch consists of a sensing element (such as a diaphragm, piston, or bourdon tube) that responds to changes in pressure. When the pressure increases or decreases to a specific set point, the switch triggers electrical contacts to open or close, thereby controlling connected equipment.

A Fireman Axe is a specialized firefighting tool designed for breaking doors, windows, and other obstacles during fire emergencies. It is an essential part of fire safety equipment used by firefighters and in industrial and commercial safety setups.

• Sharp Cutting Edge: Allows effective chopping and breaking
• Pointed Pick End (in some models): Useful for piercing and pulling materials
• Insulated Handle: Often made of rubber, fiberglass, or wood for better grip and electrical safety
• Ergonomic Design: Provides comfortable handling and better control

ABC Pressure Gauge

A pressure gauge is a small dial fitted on the extinguisher valve that shows internal pressure.

• Indicates if extinguisher is ready (green zone)
• Red zones show undercharged or overcharged condition
• Uses Bourdon tube mechanism to measure pressure
• Typically ranges from 100–250 PSI (approx.)

👉 If the needle is not in green, the extinguisher needs servicing.
