Description

Contact slide

There are already pressure switches specifically known for lighting purposes, in which the Contact member a slide in the switch base perpendicular to the push button movement and through the push-button device is a controlled insulating slide with a contact bridge. With this one At the beginning of the pushbutton movement, the switch becomes a spring seated in the slide cocked and the slider held back until the button is completely depressed is, whereupon the slide is released and moved under the action of the tensioned spring so that it makes contact between the contact springs closes or opens, in which case it is in this position after the release of the Button is locked by a link connected to it.

The present invention also relates to an imprint button switch perpendicular to the push-button movement back and forth movable contact slide and intended a particularly simple design of the switching mechanism while maintaining a momentary shift. According to the invention, the arrangement is such that the push button with a wedge-shaped tip of the push pin alternately over a surface of the wedge with the side walls of a section of the Contact slide cooperates and the latter thereby shifts, with the initiated Movement of the contact slide in one direction or the other by, on him laterally, attached helical teeth and the helical teeth of a fixed auxiliary spring momentarily is accomplished.

The drawing illustrates an embodiment of the subject matter of the invention, namely shows

Fig. Ι a view of the open switch from above,

Fig. 2 is a section in the direction AB, Fig. 3 is a section in the direction CD, Fig. 4 is a section in the direction EF, Fig. 5 is a plan view of the contact slide, Fig. 6 is its side view, Fig. 7 is its front view, Fig. 8 the control panels and Fig. 9 and 10 the push button.

The switch consists of a lower part / z and a screw-on upper part b. The lower part serves to accommodate the contact slide c, which is under the action of a spring d that adapts to the shape of its Seitenzährae h . A pressure pin / with a wedge-shaped tip g , which is under the action of a spiral spring e , is inserted into the upper part b.

The operation of the switch is as follows.

By pressing on the pin / the contact slide provided with a central recess er c is advanced from the wedge-shaped projection g by half of its way. The movement pushes the spring apart and pushes the tip of the spring tooth slightly behind the tip of the contact slide tooth. When you let go of the pin /, which is pushed back by the spiral springs, the spring pulls together and slides down the teeth h of the slide c , with the two wings of the contact slide being pushed up to the terminals.

By the same process, the contact slide c is pushed back again and thus the contact is canceled. The spring d, which is clamped into the socket, also serves to hold the contact slide c in the switching positions.

Claims (1)

Claim: Impression button switch with contact slide which can be moved back and forth perpendicular to the movement of the push button, characterized in that the push button (/) with a wedge-shaped tip (g) alternately cooperates over a surface of the wedge with the side walls of a section of the contact slide (c) and moves the latter, whereby the initiated; Movement of the slide in one direction or the other momentarily is completed by the helical teeth of a fixed auxiliary spring (d), which slide on the side helical teeth of the slider.
