Guide for Identifying Mercury Switches/Thermostats in Common Appliances
Guide for Identifying Mercury Switches/Thermostats in Common Appliances Prepared by: Jim Giordani, Burlington Board of Health, Revised 12/27/00 Contact Todd Dresser for Further information at (781) 270-1956 - 1 - Guide for Identifying Mercury Switches/Thermostats In Common Appliances This reference contains guidance for responding to a mercury spill, and how to recycle mercury bearing products. This document also contains specific recommendations for the following types of products: batteries, fluorescent lights, high intensity discharge lamps (HID) lamps, ballasts, thermostats, switches, float switches, sump pumps, silent light switches, washing machines, tilt switches, freezers, flow meters, manometers, barometers, vacuum gauges, flame sensors on gas appliances, rubber flooring containing mercury, and mercury accumulation in sanitary drains. This reference also contains a general checklist of products found to routinely contain mercury. Mercury is a dangerous element in the environment today. It can cause serious health problems such as neurological and kidney damage. Mercury is found in many products that end up in landfills and incinerators allowing the mercury to re-enter the environment and pollute drinking water and contaminate the food chain. The following information is a helpful guide to identify products that contain mercury switches and thermostats. This guide describes where mercury switches and thermostats are located and how to remove and dispose of these properly. Mercury bearing articles should not be thrown in the trash, and serious care should be taken when dealing with this element. Safe Disposal · Store mercury thermostats and switches in a suitable sturdy, sealed container. A five gallon plastic bucket with a lid may work. · Each container must be labeled "Mercury Thermostats or Switches/Universal Waste." · Be careful to keep the devices from breaking and releasing mercury into the environment. -
Looking at the Bottom of the Relay. 4 Way -- Emergency Flasher Diagram
Supplemental Wiring Information 4 Way -- Emergency Flasher Diagram The relays must be internally configured like Looking Bosch Part Number at the 30 3320015006 bottom 87A A source for this relay is the 700 of the series Volvo, most wrecking yards relay. 85 86 charge $1-$3 for a used relay. Easy 87 ID is that Volvo prints a "K" on top of the relay. 1. Run a 14 Gage wire from a fused constant hot terminal on the fuse panel to one terminal of a toggle or push/pull switch, continue on that same wire to a flasher unit and then to terminal 30 on the relay.. 2. From the other terminal of the switch, run 14 gage wire to terminal 85 on the relay. 3. Run a Black 14 gage wire from terminal 86 on the relay to a good ground. 4. Relay terminals 87 & 87A are the output terminals and must be spliced into the existing directional signal wiring, example: wire from relay terminal 87 is spliced into the left signal wires and wire from 87A into the right signal wires. The exact place to splice into the existing system may vary depending on the configuration of the existing wiring harness. Usually the easiest is where the signal wires come out of the steering column. In order for the Brake Light and Signal lights to share the same bulbs, it is necessary to isolate the the front signal lights from the rear. This is why the Turn Signal Switch has 6 wires (See below). Since I do not have an original wiring harness in my 56 Fairlane, a little trial and error may be required to determine where to splice in the wires from the relay. -
Electric Switches; Relays; Selectors
H01H CPC COOPERATIVE PATENT CLASSIFICATION H ELECTRICITY (NOTE omitted) H01 BASIC ELECTRIC ELEMENTS (NOTES omitted) H01H ELECTRIC SWITCHES; RELAYS; SELECTORS; EMERGENCY PROTECTIVE DEVICES (contact cables H01B 7/10; electrolytic self-interrupters H01G 9/18; emergency protective circuit arrangements H02H; switching by electronic means without contact-making H03K 17/00) NOTES 1. This subclass covers (in groups H01H 69/00 - H01H 87/00) devices for the protection of electric lines or electric machines or apparatus in the event of undesired change from normal electric working conditions, the electrical condition serving directly as the input to the device. 2. This subclass does not cover bases, casings, or covers accommodating two or more switching devices or for accommodating a switching device as well as another electric component, e.g. bus-bar, line connector. Those bases, casings or covers are covered by group H02B 1/26. 3. In this subclass, the following terms or expressions are used with the meanings indicated : • "relay" means a switching device having contacts which are operated from electric inputs which supply, directly or indirectly, all the mechanical energy necessary to cause both the closure and the opening of the contacts; • "driving mechanism" refers to the means by which an operating force applied to the switch is transmitted to the moving contact or contacts; • "operating" is used in a broader sense than "actuating" which is reserved for those parts not touched by hand to effect switching; • "acting" or "action" means a self-induced movement of parts at one stage of the switching. These connotations apply to all parts of the verbs "to operate", "to actuate" and "to act" and to words derived therefrom, e.g. -

Switch Wikipedia, the Free Encyclopedia Switch from Wikipedia, the Free Encyclopedia
2/24/2016 Switch Wikipedia, the free encyclopedia Switch From Wikipedia, the free encyclopedia In electrical engineering, a switch is an electrical component that can break an electrical circuit, interrupting the current or diverting it from one conductor to another.[1][2] The mechanism of a switch may be operated directly by a human operator to control a circuit (for example, a light switch or a keyboard button), may be operated by a moving object such as a dooroperated switch, or may be operated by some sensing element for pressure, temperature or flow. A relay is a switch that is operated by electricity. Switches are made to handle a wide range of voltages and currents; very large switches may be used to isolate highvoltage circuits in electrical substations. Electrical switches.

Cahier Terminologie
Francisation : terminologie disponible Francization: terminology available Nous avons le plaisir de vous informer que, dans le cadre de notre programme de francisation, un kiosque terminologique est venu s’ajouter à l’Infocentre situé près de la grande cafétéria (1F5). On pourra y consulter un cahier contenant toute la terminologie de CAE disponible à ce jour. Pour recevoir un exemplaire de ce cahier, il suffira de m’en faire la demande par téléphone (4467) ou par courriel ([email protected]). Chaque mois, il y aura également des affiches thématiques apposées sur les lieux de travail. Une rotation sera effectuée mensuellement afin de promouvoir la totalité de notre terminologie. Les thèmes abordés seront les outils de travail, la quincaillerie, les éléments d’un avion et les termes utilisés en aéronautique. Pour plus de renseignements, n’hésitez pas à communiquer avec moi. Merci de votre collaboration. Maxime Deraspe Conseiller en francisation Ressources humaines As part of our francization program, we are pleased to announce that as of today, a terminology display will be available for all employees, at the Infocentre located near the main cafeteria (1F5). This display will contain a book with all of CAE’s up to date terminology. Employees who would like to receive a copy of our terminology book can contact me at extension 4467 or by e-mail at [email protected]. Also, thematic terminology posters will be posted in the workplace each month. The posters will be rotated monthly to promote the richness of our terminology. The topics that will be highlighted include work tools, hardware, aircraft pieces and aerospace terms.
