Brass Push Pull Switch with Two Screw Terminals DC 12V 10A Marine Light Switch for Boat and RV Circuits

Some jobs do not need a relay, a fuse block or a wiring diagram. The MT128 is a brass push pull switch with two screw terminals: pull the knob for on, push for off, and the contact closes with a positive mechanical action that you can feel through your fingers.

Rated 10A at DC 12V, it covers the everyday small loads on a boat, a camper or a piece of plant — navigation lights, a cabin lamp, a horn, a small pump. Brass body, screw terminals, no crimping tool required.

• Navigation lights — Two 10W lamps draw under 2A of the 10A budget, which is why this switch has been a fixture on small boats for decades.
• Cabin and courtesy lamps — A pair of LED lamps will barely register. Even filament lamps leave room for other loads.
• Horn and small pump — Intermittent loads like a horn or a washdown pump suit a mechanical switch well, because the contact closes fully every time.
• The 120W ceiling — 10A at 12V is roughly 120W in total. Add up everything on the same circuit before the switch does it for you.

1. Strip about 6mm of insulation — Enough bare copper for the screw clamp to bite, not so much that strands bridge to the body.
2. Twist the strands, then clamp — A tidy conductor sits flat under the screw. A splayed one loses contact area and heats up.
3. One circuit per terminal pair — Do not stack two feeds on one screw to save a connector; the second wire is the one that works loose.
4. Check after a week — Screw terminals settle with thermal cycling. A second nip after the first week prevents most callbacks.

• Panel thickness matters — The stem is designed for a flat panel; a soft or oversized hole lets the switch rock and the terminals touch the panel behind.
• Reachable from the helm — Push pull is a mechanical action, so the knob should be within arm's reach without leaning past the wheel.
• Keep the terminals dry — The body is brass, but the screw terminals still benefit from being tucked up under the dash rather than in a wet well.
• Leave service slack — A short loop of cable behind the panel lets the switch be pulled forward for inspection without cutting wires.
