Embodiment Construction

[0022] According to a preferred embodiment, in figure 1 The circuit board arrangement 1 shown in is integrated in a service brake module of an electropneumatic brake system of a commercial vehicle and comprises a circuit board 2 , a circuit board carrier 4 and at least one microswitch 6 . The printed circuit board carrier 4 is here, for example, a carrier for a service brake module (not shown here).

[0023] Such a service brake module is sufficiently known, for example, from pages 876 to 877 of the Automotive Technology Pocket Book, 26th edition, 2007, by the company Rober Bosch GmbH.

[0024] In such a service brake module, in addition to the service brake pedal, components of a brake valve for single-circuit or multi-circuit operation are accommodated. Such a service brake valve has a tappet actuated by the service brake pedal, which cooperates with an axially movable, piston-shaped tappet receptacle in the housing of the service brake valve. This tappet receptacle acts a...

Abstract

The invention relates to a printed circuit board arrangement (1) having a printed circuit board (2) which can be populated with components which comprise at least one microswitch (6), wherein the printed circuit board (2) is fastened to a printed circuit board carrier (4). The invention provides for the microswitch (6) to be held between the printed circuit board (2) and the printed circuit board carrier (4) at least by means of frictional clamping owing to the normal forces caused by the fastening of the printed circuit board (2) to the printed circuit board carrier (4).

Description

technical field [0001] The invention starts from a circuit board arrangement with a component-mountable circuit board comprising at least one microswitch, wherein, according to the preamble of claim 1 , the circuit board is fastened to a circuit board carrier. Background technique [0002] A microswitch is generally understood to be an electrical switch whose contacts have a distance of less than 3 mm from one another in the open state. A known construction is, for example, a microswitch with snap-in system. In addition, designs such as normally closed and normally open switches as well as changeover switches with three connections of normally closed contact, normally open contact and tongue are known. Due to the small contact spacing, microswitches are only suitable for lightly loaded circuits. In most cases, the microswitches cooperate with the electrical and electronic circuits arranged on the circuit board. Microswitches are used in particular to generate signals repr...
