[0002] A remote control switch is a device that controls the on / off state of a circuit via wireless signals, and is widely used in homes, industries, and other fields. A remote control switch consists of two parts: a transmitter (remote controller) and a receiver (switch). The transmitter encodes the control electrical signal, then modulates it (infrared modulation, electromagnetic wave modulation, and network data signal modulation), converting it into a wireless signal and sending it out. The receiver works by receiving the radio wave signal carrying information, amplifying and decoding it to obtain the original control electrical signal, and then amplifying the power of the signal to drive relevant electrical components (thyristors, relays, etc.).

[0003] The existing remote control switch has an unreasonable internal structure layout, which is not conducive to heat dissipation of internal components. Furthermore, the internal structure cannot be integrated into a modular design, making modular assembly impossible and resulting in low assembly efficiency. Summary of the Invention

The relay module 3 includes a magnetic latching relay 31 disposed within the housing 1, a terminal block 32 disposed within the housing 1, and a first terminal 33 and a second terminal 34 disposed on the terminal block 32. The magnetic latching relay 31 is electrically connected to the control circuit board 22. One end of the first pin 311 of the magnetic latching relay 31 has a wiring portion 312 inserted into the second terminal block 34. A screw 313 connected to the housing 1 is provided on the wiring portion 312. A wire 35 is connected between the second pin 314 of the magnetic latching relay 31 and the terminal block 32. The control circuit board module adopts a modular structure design, which enables modular assembly of the control circuit board and the housing. The control circuit board is mounted on multiple support columns, which is beneficial for heat dissipation. The relay module also adopts a modular structure design, with the second terminal integrated on the first pin of the magnetic latching relay. This design is simpler, lower in cost, and enables modular assembly of the relay module and the housing.

[0026] like Figure 1 and 2 As shown, one end of the wire 35 is soldered to the second pin 314, and the other end of the wire 35 is provided with a connector lug 36. A connector screw 37 is provided on the connector lug 36, and the connector screw 37 passes through the connector hole of the connector plate 32 and is connected to the housing 1. The connector screw can fix the connector lug of the wire and the connector plate to the housing, thereby realizing the modular assembly of the wire, the connector plate and the housing, and improving assembly efficiency. A support boss 11 is provided inside the housing 1 corresponding to the connector screw 37. The upper end of the support boss 11 abuts against the connector plate 32, and the connector screw 37 passes through the connector hole and is connected to the support boss 11. The support boss provides support for the connector plate and can protect the connector plate and the housing for a tighter connection. Two positioning pieces 12 are provided on both sides of the support boss 11 inside the housing 1, and a positioning groove 120 is formed between the two positioning pieces 12. The connector plate 32 is engaged in the positioning groove 120. The positioning pieces limit the connector plate and can ensure a tighter connection between the connector plate and the housing.

[0027] like Figure 1As shown, the first terminal block 33 includes a frame 331 and a wiring bolt 332 disposed on the frame 331.

The wire clamping portion 321 is provided with multiple wire clamping grooves 3211 for clamping external cables. The wire clamping grooves increase the friction of the external cables, ensuring that the wire clamping portion can clamp the external cables tightly into the frame of the first terminal block, making the connection more secure.

[0028] like Figure 2 and 3 As shown, a support block 13 is provided inside the housing 1 at the location corresponding to screw 313. The support block 13 abuts against the wiring portion 312 of the first pin 311, and the screw 313 passes through the wiring portion 312 and is connected to the support block 13. The support block inside the housing supports the wiring portion of the first pin, ensuring a more secure connection between the first pin and the housing, and enabling modular assembly of the relay module and the housing. Two clamping pieces 14 are provided on both sides of the support block 13 inside the housing 1. The two clamping pieces 14 abut against both sides of 312 and form a limiting engagement between the first pin and the two clamping pieces 14. The two clamping pieces limit the first pin, ensuring a more secure connection between the magnetic latching relay and the housing.

[0029] like Figure 1 and 3 As shown, multiple support columns 21 have snap-fit ​​bosses 211 at one end. Multiple fixing blocks 15 arranged in a rectangular array are disposed within the housing 1. Each fixing block 15 has multiple snap-fit ​​grooves 151 that mate with the snap-fit ​​bosses 211 of the support columns 21. The snap-fit ​​bosses 211 engage within the snap-fit ​​grooves 151, forming a snap-fit ​​connection between the support columns 21 and the fixing blocks 15. The other end of each support column 21 has a threaded hole 212. A locking screw 221 connected to the threaded hole 212 is disposed on the control circuit board 22. The multiple support columns are snapped onto the fixing blocks within the housing via the snap-fit ​​bosses, enabling snap-fit ​​assembly between the multiple support columns and the housing. This allows for modular assembly of the control circuit board module and the housing, resulting in higher assembly efficiency. Furthermore, the locking screws secure the control circuit board to the multiple support columns, facilitating heat dissipation for the control circuit board.
