The invention discloses a point switch model. A box body is included. The box body is provided with a control circuit, a motor circuit and an indication circuit. An integrated control circuit includesswitches, AC relays, a polar relay, a time relay and a DC relay. The motor circuit includes DC contactors and a motor. There are four DC contactors. The indication circuit is provided with a resistor, a diode, a bidirectional Hall switch, a PLC logic circuit module and two LED indication lamps. The number of the switches is four, the four switches are two-position non-self-negative switches, thenumber of the AC relays is two, the AC relays are DFZ34J and DFZ25J respectively and are 380V AC coil relays, and the polar relay is DFZHKJ and is a 24V DC double-coil relay. The point switch model islight in weight, convenient to move, high in reliability, high in safety and quite high in practical experiment performance and reference performance.
