Size "F". 2 common 2 Normally Closed 2 Normally Open. Normally-Closed Single Pole Single Throw SPST relay In figure 1 no DC voltage is applied to points A and B therefore no current flows through the coil of the relay, the contact stays in the close position and the fan will be switched ON because it is connected to the 220V. Furthermore, the relay keeps both systems electrically isolated, greatly reducing the likelihood that any high voltage accidentally crosses-over. 4: Normally-closed, timed-closed. 4.1 out of 5 stars 12.
