19 mm momentary push button

This 19 mm momentary push button switch fits a standard 3/4 inch panel cutout and is rated for 12 V DC LED illumination at 15 mA. The aluminium zinc alloy body carries an IP67 rating, making it suitable for damp or outdoor environments. It operates as a single-pole single-throw normally-open contact rated up to 250 V AC/DC at 5 A.

Suits panels needing a lit momentary control

The switch works well for automotive, marine, computer or hobby projects that require a momentary action with a visible blue indicator. It is not intended for latching applications where the circuit must stay closed after release, nor for circuits that exceed the 5 A contact rating or the 12 V LED supply.

Handles 5 A loads with 12 V LED headroom

The contacts comfortably switch resistive loads up to 5 A at 250 V, while the separate LED circuit draws only 15 mA at 12 V. The momentary design means the circuit opens as soon as the button is released, so it cannot maintain power without continuous pressure.

Questions about this item

Does this 19mm momentary push button need a 12V power source to light the blue LED?

Yes, the LED is rated for 12V DC at 15mA and requires a 12V supply to illuminate; the switch contacts themselves are rated up to 250V AC/DC 5A and do not need that voltage to operate.

Can I use this IP67 switch alongside an older 12V system that only expects a simple on-off contact?

The switch is SPST normally open, so it closes the circuit only while pressed and adds no latching behaviour; it will work with any legacy 12V wiring that accepts a momentary contact.

How can I confirm the switch is functioning correctly after installing it in a 3/4 inch panel cutout?

Press the button — the circuit should close and the blue LED should light at 12V; release it and both the circuit and LED should turn off immediately.
