    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.

  • How Reed Relays Work Dry Reed Relays Mercury-Wetted Contact
    resistance is very low and idea for low level switching How Reed Relays work applications. The item reed relay covers dry reed relays and mercury-wetted contact relays, all of which use hermetically sealed reed switches. In both types, the reeds (thin, flat blades) serve multiple functions – as conductor, contacts, springs, and magnetic armatures. Dry Reed Relays Dry reed relays have become an important factor in the relay field. They have the advantage of being hermetically sealed and resistant to atmospheric contamination. They have fast operate and release times and when operated within their rated contact loads, have very long life. A typical dry reed switch capsule is shown in Figure 1. The disadvantages of this type of reed relay are the freezing point of mercury (-38 ° C), poor resistance to shock and vibration and the need to mount the relay in a near vertical position. These relays are used for a variety of switching applications such as found in computers, business machines, machine tool In the basic SPST-NO design, two opposing blades are sealed control systems, and laboratory instruments. into narrow glass capsule and overlapped at their free ends. The contact area is plated typically with rhodium to produce a low contact resistance when contacts are drawn together. The capsule Contact combinations. is made of glass and filled with a dry inert gas and then sealed. The capsule is surrounded by an electromagnetic coil. When the The switches used in dry reed relays provide SPST-NO, SPST- coil is energized, the normally open contacts are brought NC, SPDT contact combinations.

  • Magnetic Reed Switch Principals of Operation 8/27/2003 - Michael Mcdonald, General Manager Flair Electronics Inc
    Magnetic Reed Switch Principals of Operation 8/27/2003 - Michael McDonald, General Manager Flair Electronics Inc. Types of Reed Switches: The standard FormA Reed Switch is comprised of 2 ferromagnetic blades encapsulated in a glass tube. The glass tube is hermetically sealed with inert gas. The gas prevents any corrosion or oxidation of the switch contacts. The ferromagnetic blades of the reed switch are spaced slightly apart. The blades act as a conduit for the magnetic field. When an external magnetic field is applied to the switch, the blades will be attracted to one another. When the magnetic field strength is greater than the spring force of the blades the blades will contact, creating a physical and electrical connection between the leads. Form A Reed The standard FormC Reed Switch is comprised of 2 ferromagnetic blades with a third non-magnetic blade added to provide for a Normally Closed contact. The ferromagnetic blades of the reed switch are spaced slightly apart, with the third lead in contact with the common lead. When an external magnetic field is applied to the switch, the Common blade will be attracted to the Normally Open (NO) blade. When the magnetic field strength is greater than the spring force of the blade, the blade will contact with the (NO), creating a physical and electrical connection between the leads, while breaking the connection with the Normally Closed blade. Form C Reed How Reed switches work with magnets: Magnets have 2 poles, North & South. The reed switch operates using the potential difference of the magnetic field. If the Reed Switch is surrounded only by a North Pole (N) field the switch will not operate or close.
