Mechanical type of relays can be pretty inefficient in applications which require highly smooth, very swift and clean switching. The proposed circuit of an SSR can be built at home and used in places which require truly sophisticated load handling.A solid state relay circuit with in built zero crossing detector is described in this article. The circuit is very easy to understand and build yet

Common electromagnetic relays with coil voltage of 5V, 6V or 12V can operate power circuits in the range of 250 to 300 volts and up to 20A. The actuating current of these relays is in the range of 50 to 100 mA. In many applications, such as temperature-controlled equipment, energisation/de-energisation of 5V, 6V or 12V relays for �on�/�off� control of the load is to be achieved by a few
