The operation of the second embodiment of the present invention is explained as follows: After the coil of the relay (42) of the second control group (40) is excited, the relay switch (4 1 ) is turned off. The reed (4 5 ) will be moved to the normally open contact (413) by the magnetic field attraction (4), and the normally open contact (Μ 3) and the common contact (411) are turned on, and the power supply ( 2 〇) Providing a p-type field effect crystal U 3 ) ( 4 3 a ) a negative power source to turn on the source terminal (4 3 c ) and the 汲 terminal (4 3 b ) of the p-type field effect crystal (4 3 ). At this time, the power supply (20) provides a current loop from the second control, the group (4 〇) P-type field effect crystal (43), and flows to the inductive load (5〇), and then drives the inductive The load (5 Q) is actuated, and the current flowing out of the load (5 〇) passes through the normally closed contact (312) of the relay switch (3 i ) of the first control group (3 与) and the common contact ( 3 1 1) Conduction is transmitted, and finally, when the current is connected, the double-output resistor (2 1 ) returns to the power supply (2 Q ) to form a current loop, and the inductive load (50) starts to rotate forward. Similarly, if the first control group (30) relay and the (3 2) coil 15 1277995 are excited, the conduction switch spring (35) will be moved by the magnetic field attraction by the closed contact point (3 1 2). To the normally open contact (3丄L/d), the normal open contact (3gong3) and the common contact (31 1) are turned on this day, and the power supply (20) is provided to provide the 场-type field effect crystal. (3 3 ) The gate 鳊 (3 3 a ) of the negative electrode r , , , and s source causes the source (33c) and the 汲 terminal (33b) of the p-type field effect crystal (33) to be turned on. At this time, the power supply (2 〇) mentions #—Christine, the current loop from the p-type field effect crystal (3 3 ) passes the reverse drive inductive load (5 n ) ._ 〇), then by the inductive load (50) One block and then to the second control group (4〇) a mi cage η... U) the hoisting joint (4 12), using the p < 9 11), and then connected to the current detection power to the power supply (2 Q ) The loop is formed and the motor is negatively inverted. This day's face system _ is based on the wire effect of the field effect electric crystal material pass voltage, in addition to Y can ensure that the switching action of the field effect crystal will not have sparks. It is more normally closed and does not take the fire to cause damage to the joint. In the case where the group relay switch drives the inductive load (5◦) load action, the t relay _ also acts simultaneously, indicating that the two sets of field effect crystals are simultaneously turned on, ^ inductive negative _ is the previous charge (four) will be in two When the _ effect crystal material passes through the boundary, the object is actually connected, and it can also be transferred to the relay, the growth can be increased, and the failure of the relay caused by the malfunction can be prevented. 16 1277995 The diode (34) of the present invention (between 4 contacts and normally closed contacts, #继__=cross-contact relay switch), at this time, the original inductive load (彳(4) stops the relay excitation 4) (44) The energy stored in the power supply (20) terminal ^ will pass through the diode (3 points forming - loop, the energy of the energy storage, the energy of the common connection to disconnect the contact will also be immediately Through the diode (^ any of the relay switches, the common contact of the relay switch (4丄!)\ (4 4) transfer consumption, ^ the invention uses the first control group (3 Q), the second control group ( = Body (3 3 ) ( 4 3 ) Operation first, control: Do = move, perform - delay and restart the field effect (4), indeed ^ = = early, cost reduction; In addition, the invention of the lion two Effect crystal = the way of the normally closed contact connection of the electric switch.
