Embodiment Construction

[0011] The push button switch has a housing 10 made of plastic and is installed in the housing 10 and can be used as figure 1 usual location shown and figure 2 The push button 12 is axially actuated between the depressed positions shown. At the bottom of the housing 10, there are two microswitches 14, 16 arranged in parallel next to each other. On the microswitches 14 , 16 , a two-arm switch actuating rocker with a transmission arm 18 and an actuating arm 20 is mounted rotatably around an axis A in the housing 10 . Axis A is perpendicular to the starting direction of button 12 figure 1 indicated by the arrow. from image 3 As can be seen in Fig. 1, the trigger arm 20 is branched, having two parallel legs 20a, 20b. At the opposite end of the housing 10 away from the button 12, it is provided as a socket with protruding contact posts.

[0012] A single-armed cam lever 22 is disposed axially beside the button 12 . This lever 22 generally extends in the direction of actuat...

Abstract

A push button switch has a housing (10) and a push button (12) installed in the housing (10) that can move axially between a normal position and a compressed position. The push button is loaded in the normal position and driven by a spring. a resiliently mounted cam member (24), at least one microswitch (14) mounted in the housing, and a switch actuating rocker mounted in the housing 10 for axial action, the switch brake rocker having a The braking arm (20) of the microswitch (14) and the transmission arm (18) engaged by the cam member (24) are used to maintain the execution rocker in the normal position when the button is in the normal position. In the normal position, when the button is initially pressed, the moving brake arm moves away from the microswitch. As soon as the button moves to its pressing position, the actuating arm moves to the position of executing the microswitch, and as soon as the button returns to the normal position from the pressing position, the rocker is forced to execute. rod to its usual position.

Description

technical field [0001] The invention relates to a push button switch for a motor vehicle, in particular for starting the parking brake of a power supply electric motor. Background technique [0002] In the traditionally designed push button switch, the electromechanical switch mechanism is directly actuated by the starting part arranged on the button. Such pushbutton switches will be damaged if undue force is applied by the pushbutton. [0003] Also, for a pushbutton switch for a specific application, two backup circuits independent of each other are required, and they are activated simultaneously in a very short time. An example is the above-mentioned parking brake for starting a powered motor. Due to unavoidable deviations, a great deal of effort has to be made to satisfy the simultaneous and fast start of both circuits. Contents of the invention [0004] The invention provides a push button switch which is not sensitive to excessive starting force and enables synchro...
