Abstract

The invention discloses an electromagnetic type power master switch for a car. According to the key points of the technical scheme, the electromagnetic type power master switch for the car comprises an electromagnetic component, a metal shell, a movable iron core, a movable contact component and a fixed electrode. The electromagnetic component is mainly composed of a magnetism conducting plate, a coil holder, a primary coil and an auxiliary coil, wherein the primary coil and the auxiliary coil are arranged on the coil holder, the auxiliary coil is arranged at the outer side of the primary coil, a thermistor is connected to a closed circuit of the auxiliary coil in series, and the thermistor is fixed inside a groove of bakelite through 906 insulation paste. The primary coil and the auxiliary coil are provided, the thermistor is connected to the closed circuit of the auxiliary coil in series, and therefore the electromagnetic type power master switch for the car achieves the effects of reducing energy consumption, lowering pull-in voltage, lowering a heat value and reducing material consumption.

Description

technical field [0001] The invention belongs to the technical field of a power master switch, and in particular relates to an electromagnetic power master switch for a vehicle. Background technique [0002] At present, the conventional main power switch uses a push rod (that is, a moving iron core) to drive the contact piece to make the moving contact piece and the fixed electrode connected or disconnected to realize the switch control of the automobile power supply, wherein the radial movement of the push rod Restricted, but relatively free in axial movement, the magnetic force generated by the coil energization promotes the attraction of the movable contact member and the fixed electrode to realize the connection of the power supply. However, the main power switch currently used is mostly a single set of coils, and the power when the coil is pulled in is as large as the power when it is held, and the main switch of the power supply is in the holding stage after the pull-in...
