Each of the two second terminals 25 includes a wiring frame 251 and a wiring bolt 252 disposed on the wiring frame 251. The two pins 231 of the relay 23 are respectively inserted into the wiring frames 251 of the two second terminals 25, and the wiring bolts 252 of the two second terminals 25 respectively abut against the two pins 231, and a wiring space 250 is formed between the two pins 231 and the wiring frames 251 of the two second terminals 25. The circuit board module adopts a modular structure design, with the relay, first terminal block, and second terminal block integrated on the power circuit board. This facilitates the assembly of the circuit board module with the housing and enables modular assembly. Furthermore, the two second terminal blocks are integrated on the two pins of the relay, simplifying the structural design. The second terminal blocks also adopt a wiring frame structure design, which enhances the current carrying capacity, allowing the current rating to reach 40A. Thus, this time control switch can meet the requirements for high-current applications.

[0027] like Figure 1 , 2As shown, a removable battery 221 is mounted on the main circuit board 22. The battery features a removable design, facilitating user replacement. When the power is disconnected, the battery provides power to the main circuit board and temporary power to the control chip and clock module, ensuring that critical information such as timing data and preset programs are not lost. Each of the two first terminals 24 includes a terminal 241, a terminal screw 242 mounted on the terminal 241, and a conductive plate 243. One end of the conductive plate 243 is inserted into the terminal hole 240 of the terminal 241, and the other end is connected to the power circuit board 21. The two first terminals are connected to the power circuit board via the conductive plates, facilitating assembly and making assembly more convenient. The housing 1 includes a bottom shell 11, an upper shell 12 and a cover 13 disposed on the bottom shell 11. The bottom shell 11 and the upper shell 12 are each provided with a snap-fit ​​block 101 that mates with the cover 12. The cover 13 is provided with a snap-fit ​​hole 131 that mates with the snap-fit ​​block 101. The snap-fit ​​block 101 engages within the snap-fit ​​hole 131, forming a snap-fit ​​engagement between the bottom shell 11, the upper shell 12 and the cover 13. A receiving cavity 100 for accommodating the circuit board module 2 is formed between the bottom shell 11, the upper shell 12 and the cover 13. The snap-fit ​​between the bottom shell, the upper shell and the cover improves the assembly efficiency of the housing. The main circuit board 22 is provided with multiple buttons 222. The cover 13 is provided with button holes 132 through which the multiple buttons 222 pass. A button waterproof gasket 14 is provided between the cover 13 and the multiple buttons 222.

A transparent cover plate 15 is provided on the cover 13 and engages with the display window 133. Multiple buttons and a display screen are provided on the main circuit board to facilitate user operation.

[0028] like Figure 2 and 5 As shown, two positioning slots 111 are provided inside the bottom shell 11 at the two pins 231 of the relay 23, respectively. The two pins 231 of the relay 23 are respectively engaged in the two positioning slots 111, forming a snap-fit ​​connection between the relay 23 and the bottom shell 11. The two pins of the relay are engaged in the two positioning slots of the bottom shell, which facilitates the assembly of the relay and the bottom shell, making assembly more convenient. Two limiting strips 121 are provided inside the upper shell 12 at the two pins 231, respectively. When the upper shell 12 is closed on the bottom shell 11, the two limiting strips 121 abut against the two pins 231. The upper shell presses the two pins of the relay into the positioning slots of the bottom shell through the limiting strips, and the upper shell and the bottom shell are riveted together by multiple rivets, thereby ensuring a tighter connection between the relay and the shell.

[0029] like Figure 2 and 4As shown, the housing 1 is provided with a guide rail groove 102. A guide rail fastener 16 is slidably mounted on one side of the housing 1 corresponding to the guide rail groove 102. Two elastic limiting arms 161 are symmetrically arranged on the guide rail fastener 16. A limiting protrusion 103 is provided on the housing 1 between the two elastic limiting arms 161. On both sides of the limiting protrusion 103 are respectively provided an unlocking limiting slope 1031 and a locking limiting slope 1032 that cooperate with the two elastic limiting arms 161. An arc surface 1033 transitions between the unlocking limiting slope 1031 and the locking limiting slope 1032. The guide rail fastener 16 drives the two elastic limiting arms 161 to reciprocate between the unlocking limiting slope 1031 and the locking limiting slope 1032. The guide rail fastener on the housing allows for rail-mounted installation of the time switch, making installation more convenient. Furthermore, the guide rail fastener uses two elastic limiting arms to lock and unlock with the guide rail, resulting in a simpler and lower-cost design. Guide protrusions 162 are provided on both sides of the guide rail fastener 16, and a guide groove 104 is provided on the housing 1 to cooperate with the guide protrusions 162. The guide protrusions 162 are slidably disposed within the guide grooves 104. The guide rail fastener is slidably disposed within the guide grooves of the housing via the guide protrusions, facilitating the assembly of the guide rail fastener with the housing and ensuring reliable operation of the guide rail fastener on the housing.
