Reed Switches in Automobile Relays
Reed Switches find various applications in automobile electronics, for signal switching using reed relays, and in overheat protection using thermal reed sensors. Miniature reed relays, capable of switching high loads are used in automobile climate control circuits to switch on or switch off the heater and air conditioning circuits, for controlling the turn signals, and in applications for overload protection and safety. A well designed Reed Relay can consistently work at the require operate voltage range for hundreds of thousands of operations. In addition to Reed Relays, Thermal reed sensors are also used in automobiles to as a safety cut-out when the electronics on the control circuits cross a set temperature.
