Embodiment approach

[0132] In addition, in each of the above-mentioned embodiments, the first switch element 41 and the second switch element 42 are integrated or formed into one unit, but the concept of the present invention is not limited to this form. For example, it can also be used as Figure 9 As shown, the first switch unit 51 of the accommodated first switch element 41 and the second unit 52 of the accommodated second switch element 42 are arranged side by side, so that the switch operation parts of each unit 51, 52 (for the first unit 51 The upper protrusion 51b of the slider 51a, which is the operation protrusion 52a for the second unit 52, is fitted into the two recesses 50a, 50b of the knob (corresponding to the knob 3 in the above-mentioned prior art).

[0133] According to aspects 1 to 3 of the present invention, the contact of the second switch element is turned off at an appropriate timing, thereby cutting off the passage of instantaneous large current and preventing the contact o...

Abstract

A switch device for rotating and stopping a DC motor includes a first switch element having two moving contacts, two normally open NO contacts and two normally closed NC contacts, a second switch element having one or two normally closed NC contacts, and an operating element. The operating element serves to connect the two moving contacts individually to input terminals of the DC motor, the two NO contacts to a voltage source line at a higher voltage, and each of the two NC contacts of the first switch element to another voltage source line at a lower voltage such as the ground potential, each through the NC contact, or one of the two NC contacts, of the second switch element. The NC contact of the second switch element is maintained in an open condition during a period from when either one of the NO contacts begins to change from a closed condition to an open condition until the corresponding NC contact of the first switch element finishes changing from an open condition to a closed condition.

Description

technical field [0001] The present invention relates to, for example, a DC motor used for opening and closing windows of vehicles such as automobiles or a switching device for turning and stopping a DC motor similar to it, and particularly relates to a DC motor suitable for operation on a high power supply voltage (42V series electric system) best switching device. Background technique [0002] Although the current automobile uses a 14V series electrical system (power supply voltage: 12V), due to the increase in the number of electronic devices installed, the 14V series will consume electric power and cannot be continuously supplied. In order to solve this problem, according to the results of continuous global discussion by the international consortium of the contract between the production department and the school, the electric system of the "42V series" (power supply voltage: 36V) can be consistent. [0003] An example of an electrical product operating as a 42V series ...
