RELAY START TECUMSEH 82467 W/SCREW

Relays are electrical devices that are used to control circuits in restaurant equipment and other types of machinery. They work by using a small electrical current to control a larger current, allowing a low-power control circuit to switch a high-power circuit on or off.

In restaurant equipment, relays can be used to control a variety of functions, such as turning on and off motors, controlling heating elements, and activating alarms. For example, a relay might be used to turn on a refrigerator's compressor when the temperature inside the fridge reaches a certain level, or to turn off a stove's heating element when the temperature reaches a certain point. Relays are often used in restaurant equipment because they can handle large amounts of current and are able to switch circuits on and off quickly and reliably.

A screw is a type of fastener, in some ways similar to a bolt typically made of metal, and characterized by a helical ridge, known as a male thread (external thread). Screws are used to fasten materials by digging in and wedging into a material when turned, while the thread cuts grooves in the fastened material that may help pull fastened materials together and prevent pull-out.

A screw drive is a system used to turn a screw. At a minimum, it is a set of shaped cavities and protrusions on the screw head that allows torque to be applied to it. Usually, it also involves a mating tool, such as a screwdriver, that is used to turn it. Other examples include Phillips head screws and screwdrivers, and Allen hex screws and wrenches.
