Micro Relay Switches
A relay switch is an electrically operated switch that is used in applications that require the control of a circuit by a low-power signal, where the control and controlled circuits must be electrically isolated from one another. Relay circuit switches are found in most vehicles driving along our roads today. They are most commonly used to enable a low amperage circuit switch On or Off a higher amperage circuit. The most frequent example of this is probably the switching on of the vehicle's head lights.
It is unadviseable to hook up directly the headlights to the headlight switch as this could exceed the amperage rating of the switch. In such an event, the unwanted risk of causing an electrical fire or damaging cable wires may be encountered.
Micro Relay Switches - Multiple Switching
Relays can also be used to facilitate the switching of multiple components at the same time using a single output. A single output connected to multiple relays will allow you to open continuity and/or close continuity simultaneously - a very useful function.
