A relay is an electrically operated switch.Many relays use an electromagnet to mechanically operate a switch, but other operating principles are also used, such as solid-state relays.Relays are used where it is necessary to control a circuit by a separate low-power signal, or where several circuits must be controlled by one signal..

These are high quality Single Pole - Double Throw (SPDT) sealed relays. Use them to switch high voltage, and/or high current devices. This relay’s coil is rated up to 12V, with a. Automotive SPDT Relay and Harness - What are they and how do I use them Relay (SPDT - Single Pole Double Throw) - Is an electromagnetically device which has a energize able coil. Relays are used in a wide variety of applications within automobiles.. These are massive single pole - double throw (SPDT) sealed relays. This means that when current is applied to the coil it throws a simple changeover switch, terminating the connection from the NC contact to ground and closing the NO contact..

This is the diagram below to learn all the pin terminals of a Double Pole Double Throw (DPDT) Relay: The 2 COIL terminals is where the voltage is placed in order to energize the coil. Place the relay's rated coil voltage on these terminals. The polarity of the voltage does not matter. A positive and. In electrical engineering, a switch is an electrical component that can "make" or "break" an electrical circuit, interrupting the current or diverting it from one conductor to another. The mechanism of a switch removes or restores the conducting path in a circuit when it is operated. It may be operated manually, for example, a light switch or a keyboard button, may be operated by a moving. SPST vs SPDT Relays. What’s the difference? Single Pole, Single Throw (SPST): This relay will be identified as having a middle 87b spade (or no middle spade at all).This is the most common relay used for fog lights or other simple circuits..

This correlates to the following in the relay: Terminal Descriptions. COIL- This is one end of the coil. COIL- This is the other end of the coil.These are the terminals where you apply voltage to in order to give power to the coils (which then will close the switch).. Getting Electronic Parts. There are several suppliers of electronic parts that advertise in Model Railroader and other model train magazines..
