The process of a boiler's heating operation begins when the room that is being heated gets cold. At this point, the thermostat sends an electrical signal to the relay switch. The relay then triggers the boiler to turn on. lan aber kein wlan jetbrains academy javascriptSplet20. mar. 2016 · It depends on the relay. But they usually take around 10ms (milliseconds) to switch on, or off. So about 100 flips per second (50 Hz). BUT such "fast" switching rates (for relays), is NOT a good idea. Also mechanical switching life, is usually around (1 to 100) million switch cycles (NOT electrically loaded). lana berry kids
