Abstract
The invention discloses a differential lock signal control switch which comprises a cylindrical shell body, a gland assembly, an indenter assembly and a breakover assembly, wherein the gland assembly, the indenter assembly and the breakover assembly are arranged in the shell body. The shell body is used as a negative electrode of a switch. A wiring inserting piece in the gland assembly is used as a positive electrode of the switch. The shell body and the wring inserting piece push a pressing cap to move towards an adjusting screw by pushing a push rod to drive a second compression spring to move together with the pressing cap in work. When the pressing cap contacts the adjusting screw, an current signal forms a closed loop circuit through the wiring inserting piece, the adjusting screw, the pressing cap, the second compression spring, the push rod, a first compression spring, the shell body and an automobile brake axle. A signal control switch is switched on. The differential lock signal control switch has the advantages of overcoming the defects that an existing differential lock signal control switch is complicated in structure, high in cost, unfirm in installation and use of wires, and being simple in structure, low in manufacturing cost, stable and reliable in work and the like.
