16 mm IP67 momentary pushbutton
The JacobsParts LTCH-O3-BLU is a 16 mm aluminium momentary pushbutton rated for 12 V DC and 3 A switching. It fits a 16 mm panel cut-out and includes a metal nut plus an optional rubber O-ring for sealing. The blue LED can be wired independently so it stays lit or lights only when the button is pressed. It suits automotive, marine and electronics-project panels that need a compact, weather-sealed control.
IP67 sealing and low heat
The switch body is rated IP67, so it withstands heavy rain, splashes and temporary immersion without ingress. Aluminium zinc-alloy construction conducts heat away from the contacts during normal 3 A operation, keeping the actuator cool to the touch. The LED draws only 15 mA at 12 V, adding negligible thermal load and no audible noise in typical dashboard or enclosure installations.
Sustained 3 A at 250 V rating
The contacts are rated for 250 V AC/DC at 3 A continuous, so the switch handles prolonged actuation without derating within the -20 °C to 55 °C operating range. Momentary action means the circuit closes only while the button is held, preventing unintended latch-on during vibration. The SPST normally-open design ensures a clean break each time the actuator is released, even after extended use.

Questions about this item
How do I install the 16mm momentary pushbutton and which step is often missed?
Drill a 5/8" hole, thread the switch through, secure with the metal nut from the back, and fit the rubber O-ring between the neck and panel face for IP67 sealing — the O-ring is the step most installers forget.
What maintenance or replacement will this switch need over time?
The LED is rated at 12V DC 15mA; if it dims or fails you can rewire it independently because the LED circuit is separate from the 3A switch contacts.
What limit appears first during sustained use?
The operating temperature ceiling of 55°C is reached before the 3A contact rating becomes a constraint in continuous duty.
