A Single-Pole, Single-Throw (SPST) mercury switch on millimetre graph paper, device length approximately 1.5 cm Another mercury switch design. A mercury switch is an electrical switch that opens and closes a circuit when a small amount of the liquid metal mercury connects metal electrodes to close the circuit.
An outboard motor is a propulsion system for boats, consisting of a self-contained unit that includes engine, gearbox and propeller or jet drive, designed to be affixed to the outside of the transom. They are the most common motorised method of propelling small watercraft.
The outdrive resembles the bottom half of an outboard motor and is composed of two sub-units: an upper containing a driveshaft connected through the transom to an engine which transmits power to a 90-degree-angle gearbox; and the lower containing a vertical driveshaft receiving power from the upper unit gearbox, transmitted through another 90 ...
A timing mark is an indicator used for setting the timing of the ignition system of an engine, typically found on the crankshaft pulley (as pictured) or the flywheel. [1] These have the largest radius rotating at crankshaft speed and therefore are the place where marks at one degree intervals will be farthest apart.
Thermal switches on microprocessors often stop only the fetching of instructions to execute, reducing the clock rate to zero until a lower temperature is reached, while maintaining power to the cache to prevent data loss (although a second switch, with a higher triggering temperature, usually turns off even the cache and forces the computer to ...
The BF115, 130, and 150 engines uses a power head based on the same 2.4L K24 VTEC engine used in the Honda Accord. The BF200, 225, and 250 use engines derived from Honda's J35A series of engines used in larger vehicles such as Pilot, Odyssey, and Ridgeline. Honda offered a five-year no-declining warranty on their engines.
The first, in 1952, was RPM Manufacturing Company of Missouri, whose specialty was a rotary power mower that Outboard planned to sell under its familiar Lawn-Boy tradename. Featuring a detachable engine useful as an outboard, the mower was already a best-selling unbranded item in both the Sears and the Spiegel catalogs.
Car engine thermostat. Perhaps the most common example of purely mechanical thermostat technology in use today is the internal combustion engine cooling system thermostat, used to maintain the engine near its optimum operating temperature by regulating the flow of coolant to an air-cooled radiator. This type of thermostat operates using a ...
