19 mm IP67 momentary pushbutton

This 19 mm panel-mount switch provides a momentary, normally-open contact rated at 250 V AC/DC and 5 A. The blue LED operates at 12 V DC drawing 15 mA and can be wired to stay lit continuously or only while the button is pressed. Its IP67 rating and aluminium zinc alloy body suit automotive, marine and industrial environments.

Fits 19 mm cutout with screw terminals

Installation requires a 19 mm (3/4 inch) drilled hole; the threaded neck secures with the supplied metal nut and optional rubber O-ring for extra sealing. Screw terminals accept ring or fork lugs, freeing the builder from soldering. Total depth behind the panel is 40 mm including contacts, so allow that clearance in the enclosure.

Stays within -20 °C to 55 °C under continuous load

The switch is rated for sustained operation across a -20 °C to 55 °C ambient range while carrying the full 5 A at 250 V. The LED runs at a constant 12 V DC 15 mA without thermal derating. Momentary action means the circuit closes only while the actuator is held, so no latching heat build-up occurs during prolonged actuation.

Questions about this item

How long can the switch handle a continuous 5 A load before the 55 °C temperature limit becomes a concern?

The switch is rated for operation up to 55 °C; sustained 5 A current will generate heat, so ensure the panel and wiring keep the body below that temperature during continuous use.

Does the blue LED or the switch body produce noticeable heat or noise during all-day operation?

The LED draws only 15 mA at 12 V and the mechanical switch is silent; neither component generates audible noise or significant heat under normal all-day use.

What panel thickness and cut-out size must the mounting surface already have for this switch to fit?

The switch requires a 19 mm diameter cut-out and a panel thick enough to accommodate the 17.5 mm thread depth plus the included metal nut and optional O-ring.
