INVENTORS EDWARD V. SAHRBACKER JULIUS E WI ED ATTOR SWITCH ASSEMBLY This invention relates to electric switches and more particularly to electric switches having a slide button for actuating the switch.

In prior slide button switches, difficulty has been encountered in detachably retaining or securing the slide button in one or more of its reciprocable positions. A further problem has been to effectively guide and limit the reciprocable travel of the slide button.

Therefore, it is an object of the invention to provide a reciprocable slide button electric switch wherein the slide button may be detachably retained in any one of its reciprocable positions.

A further object of the invention is to provide a slide button switch of the above type having guide means to guide and limit the reciprocable travel of the slide button.

A further object of the invention is to provide a pushbutton electric switch that is simple in construction, economical to manufacture, and highly effective in operation.

Briefly, the foregoing objects are accomplished by the provision of a slide button electric switch having a reciprocable slide button to actuate the switch. The switch includes a switch casing, a trigger actuated switch device in the casing, and a contact carrier disposed in the casing for reciprocation therein along the longitudinal axis of the carrier. The contact carrier contains a portion of the switch device whereby reciprocation of the contact carrier actuates the switch device..A slide button is reciprocably positioned on the casing and is operatively connected to the contact carrier whereby reciprocation of the slide button reciprocates the contact carrier thereby actuating the switch device. Releasable stop means for detachably retaining the slide button in at least one of its reciprocable positions is also provided.

More specifically, the releasable stop means includes a slide bar disposed in the casing between the contact carrier and the slide button, whereby the contact carrier slides on the undersurface of the slide bar. The slide bar has at least one prepositioned aperture therein. Bias means is disposed in the contact carrier effecting a bias against the slide bar. The bias means has an abutment on its end abutting the slide bar whereby the abutment partially enters the slide bar aperture and is releasably retained therein by the bias means when the slide button is disposed in its one reciprocable position. More such reciprocable stop positions may be added by adding more prepositioned apertures to the slide bar.

The slide button is guided in its reciprocable travel. More specifically, the casing has an elongated slot therein adjacent the slide button, and said slide button has a lug slidably disposed in said slot to guide and limit the reciprocable travel of the slide button.

Thus, the invention provides a simple, economical, effective, electric slide button portable tool switch wherein the slide button may be releasably retained in any one of a plurality of reciprocable positions. The slide button is guided in its reciprocable travel by the above slot-lug structure that also limits the travel of the button.

Other objects and advantages of the invention will be apparent from the following description taken in conjunction with the drawings wherein:

FIG. 1 is a side elevational view of an electric pushbutton portable tool switch constructed in accordance with the invention;

FIG. 2 is a view taken along the line 2-2 of FIG. 1;

FIG. 3 is a view taken along the line 3-3 of FIG. 1;

FIG. 4 is an enlarged view taken along the line 4-4 of FIG. 2;

FIG. 5 is an enlarged view taken along the line 5-5 of FIG. 4; and

FIG. 6 is an enlarged view taken along the line 6-6 of FIG. 5.

Although the invention is shown and described herein with reference to its application in portable electric tools, it will be understood that it may be used in any application to control the application of electrical energy to an applied load.

The terms and expressions which have been employed are used as terms of description, and not of limitation, and there is no intention, in the use of such terms and expressions, of excluding any equivalents of the features shown and described or portions thereof, but it is recognized that various modifications are possible within the scope of the invention claimed.

Referring to the drawings, there is shown an electric switch for portable electric motor-driven tools including a switch casing 10, a trigger actuated switch device 12 disposed in the casing, and a contact carrier 14 disposed in the casing for reciprocation therein along the longitudinal axis of the carrier. The switch device 12 is disclosed and claimed in the assignees application Ser. No. 702,272 entitled Electric Switch, filed on Feb.

l, 1968, now Pat. No. 3,536,973, issued Oct. 27, 1970.

Such switch 12 will not be further described in detail as the same, per se, forms no part of the present invention.

The contact carrier 14 contains a portion of the switch device 12 whereby reciprocation of the contact carrier actuates the switch device. A slide button 16 is reciprocably positioned on the casing and is operatively connected to the contact carrier 14 whereby reciprocation of the slide button reciprocates the contact carrier thereby actuating the switch device 12. Releasable stop means for detachably retaining the slide button 16 in at least one reciprocable position is provided, now to be described.

The releasable stop means includes a slide bar 20 which is disposed in the casing 10 between the contact carrier 14 and the slide button 16, whereby the contact carrier slides on the undersurface of the slide bar. The slide bar has at least one prepositioned aperture 22 therein. Bias means in the form of a compressed coiled spring 24 is disposed in the contact carrier 14 effecting a bias against the slide bar 20. The bias means 24 has a spherical abutment 26 secured on its end abutting the slide bar 20 whereby the abutment partially enters the slide bar aperture 22 and is releasably retained therein by the bias means 24 when the slide button is disposed in such one reciprocable position as shown in FIG. 6.

It will be understood that the slide bar may contain more than one of such apertures 22 to provide a plurality of releasable stop positions for the slide button 16 if required.

Guide means are provided for guiding and limiting the travel of the slide button 16 as it reciprocates. More specifically, the guide means includes a lug and slot structure on each side of the casing 10 and the slide button 16, wherein the casing has an elongated slot 30 therein adjacent the slide button, and the slide button has a lug 32 slidably disposed in the slot 30 to guide and limit the reciprocable travel of the slide button.

What is claimed is:

1. An electric switch for portable electric motordriven tools comprising, a switch casing, a trigger actuated switch device disposed in the casing, a contact carrier disposed in the casing for reciprocation therein along the longitudinal axis of the carrier, said contact carrier having a pair of side-by-side, elongate, parallel channels in the underside thereof, each containing a portion of the switch device whereby said reciprocation of the contact carrier actuates the switch device, a pair of upstanding bosses on the top of said contact carrier approximately intermediate the ends thereof and extending upwardly through a pair of parallel slots in the casing, a vertically extending bore in each of said bosses and opening downwardly into a respective one of said channels, coil spring means in each bore and engaged with a respective switch device to urge the switch device downwardly into operative position, a slide button reciprocably positioned on the casing and having a downwardly extending wall along the opposite sides thereof, each wall projecting downwardly through a slot in said casing and having an outwardly projecting guide lug on the bottom edge thereof received in guide slots at opposite sides of the casing, said guide lugs engaging stop means at the opposite ends of the slots to limit travel of the contact carrier, each of said upstanding bosses on said contact carrier received at their upper ends in a socket on the underside of the slide button to operatively connect the slide button to the contact carrier whereby reciprocation of the slide button reciprocates the contact carrier thereby actuating the switch device, and releasable stop means for detachably retaining the slide button in at least one of its reciprocable positions, said stop means including a slide bar in the casing between the contact carrier and slide button, a plurality of apertures in said slide bar, a movable abutment carried by the contact carrier between the contact carrier and slide bar, and bias means carried by said contact carrier in engagement with said abutment to urge said abutment toward and into said apertures.
