The shell 1 is formed by jointing an upper shell 1a and a lower shell 1b, a splicing groove 3 is formed in one side part of the shell 1, a circuit board 4 is spliced in the splicing groove 3, a safety module 5 and an indicator light module 11 are integrated on the circuit board 4, a first pin 6, a second pin 7, a third pin 8 and a fourth pin 9 are arranged on the shell 1 in the same direction, each pin is clamped and fixed by the upper shell 1a and the lower shell 1b and protrudes out of four pins on the outer side of the shell 1, two pins are respectively connected with a positive electrode and a negative electrode of a power supply, if alternating current is connected, the positive electrode and the negative electrode are not separated, the other two pins are respectively connected with a small load 10, the three pins are connected with the circuit board 4, and the power on-off between the two pins is controlled by a button component 2. The four pins may be defined differently by modifying the circuit board circuitry, such as one: the middle two pins are connected with a power supply, and the other two pins are connected with a small load; two can be defined: the middle two pins are connected with a small load, and the other two pins are connected with a power supply, so three can be defined: the two pins on the left side are connected with a small load, and the two pins on the right side are connected with a power supply; or define others. As illustrated in fig. 1 and 3, the first pin 6 and the fourth pin 9 are respectively connected with the positive electrode and the negative electrode of the power supply, the first pin 6 and the second pin 7 are connected through the safety module 5 on the circuit board 4, one end of the second pin 7 and one end of the third pin 8 are connected through the circuit board 4, the other end of the second pin 7 and the other end of the third pin 8 are connected with the small load 10, and the on-off between the third pin 8 and the fourth pin 9 is controlled by the button assembly 2.
