Buying guide
Specifying a metal push button
The mounting hole comes first
These are specified by the panel hole they fit — 16mm, 19mm, 22mm, 25mm or 30mm — not by the size of the cap you can see. Measure the hole in your enclosure before ordering. Everything else, including illumination and latching behaviour, can be chosen afterwards.
Momentary or latching changes what the circuit does
A momentary button makes contact only while held: start buttons, doorbells, exit buttons, gate controls. A latching button stays in position until pressed again: power switches and isolators. Ordering the wrong one is not something you can fix with wiring.
NO or NC decides what pressing the button does
Normally Open completes the circuit when pressed. Normally Closed breaks it. Emergency stop circuits use NC deliberately, so that a cut wire produces the same result as pressing the button. Fail safe, not fail silent.
LED illumination needs its own supply voltage
The ring or dot on an illuminated button is a separate circuit from the contacts, and it has its own voltage — commonly 12V or 24V DC. Wiring it to the switched load instead of a supply is why an LED button sometimes lights only when the circuit is already on.
Frequently asked questions
How much does a metal push button switch cost in Pakistan?
At ZZ Marts, a 16mm metal push button with LED ring costs Rs 450, 19mm buttons Rs 550–700, a 22mm button with RGB LED Rs 750, and 25mm or 30mm buttons with green LED ring (latching or momentary) Rs 1,350–1,500.
What size metal push button switch do I need?
Measure the mounting hole diameter in your panel. Standard sizes are 16mm, 19mm, 22mm, 25mm and 30mm. The visible cap is wider than the hole, so measure the hole, not the button.
What is the difference between momentary and latching switches?
Momentary makes contact only while pressed and releases when let go. Latching stays in its new position until operated again. Start buttons and exit buttons are momentary; power isolators are latching.
What is the difference between NO and NC contacts?
Normally Open completes the circuit only when pressed. Normally Closed breaks a circuit that is otherwise complete. Emergency stops use NC so that a broken wire triggers the same safe result.
How do I wire an illuminated push button?
The LED is a separate circuit from the contacts and needs its own supply at its rated voltage, usually 12V or 24V DC. Check the terminal markings before connecting.
Do you sell switches in trade quantities?
Yes. Send the part number and quantity on WhatsApp for trade pricing, or buy single switches online or at the Karachi and Lahore stores.
