Abstract
The utility model discloses a differential lock signal control switch, which comprises a straight-tube-shaped housing. The differential lock signal control switch further comprises a gland assembly, a pressure head assembly and a conduction assembly all arranged inside the housing. The housing serves as the cathode of the switch while a wiring insert sheet inside the gland assembly serves as the anode of the switch. During a working process, a second compression spring and a pressure cap are driven through a push rod to move together. The pressure cap is then driven to move towards an adjusting screw. Once the pressure cap contacts the adjusting screw, current signals then pass through the wiring insert sheet, the adjusting screw, the pressure cap, the second compression spring, the push rod, a first compression spring, the housing and an automobile brake axle to form a closed loop. The signal control switch is then turned on. The switch provided by the utility model overcomes the defects existing in a conventional differential lock signal control switch and characterized by complex structure, high cost, unfixed lead wire installation and lead wire using instability, etc. Furthermore, the differential lock signal control switch has the characteristics of simple structure, low manufacture cost, and working stability and reliability, etc.
