H.. P. BALL. SNAP SWITCH. APPLICATION FILED DEQ. 4, 1905.
.- Patented Feb. 1, 1910.

' which enter the spaces between the side arms site sides of the central aperture and-pau which the springs may Iplay freely. At opl of contact blades 26 in alinement with the i respective stationary contactclips 2, and to each blade 26 is securedY a U-shaped clip 27 ada ted to receive and securely hold the metallic end of a cartridge fuse 28. Theblock 21-carries a yoke 29 of the form shown in Fig. -6 and arranged thereon so that its 'opposite ends extend across the central aperture 22 near the top and bottom surfaces of the block in ositions to be engaged by the 'respective' en s of the latch 17. The lower end of the yoke 29l has two pairs of lugs 30 12 and the H-shaped posts 14 and, when the movable member is inA closed position, rest upon stops 31 formed by bendingin lugs near the lower ends ofthe side arms 12.
The actuator4 consists of two bars 32 connected at their outer ends and provided with a suitable grip plate 33, and extending through the bars 32 are longitudinal slots 34 for the reception of rods 35 to' which the helical springs 3G are attached. The bars 32 are supported at their outer ends by the guide plates 15 and at their inner ends by the U-shaped guides 13 ot the guide frame. When'the switch is in open position, as shown in Fig". 3, the latch 17 engages at its outer end with outer end ofthe yoke 29. By forcing the actuator toward the base the inner rod 35 engages the outer ends of its corresponding slots 34 and is carried inwardly therewith while the outer rod 35 rests upon the outer end et the yoke.29 and is held from movement. .The springs 3G are thus gradually tensioned until the outer end of the latch 17 is moved out of the-path of the yoke 2S), which is effected by the crowding of the inner end of the latch back by the engagementl therewith of the inner rod 35. As soon as the latch clears the outer' end of the yoke the springs 3G react and t carry the movable member with a snap action to closed position with the inner end of the oke 29 lying beyond the inner end of the .atch 17 and resting upon the stops 3 1. Vhen it is desired to open the switch the actuator is pulled out and the steps above described are repeated in inverse order, the inner rod 35 being` held stationary and the outer rod y35 moving' with the actuator and putting the springs under tension.
I do not desire to restrict'myself to the particular form or arrangement of parts herein shown and described, since it is ap parent that they may be changed and modified without departing from my. invention.
that I claim as new, and desire to seouri` by Letters Patent of the United States, is,-
il. The combination with a base provided with stationary. cont-acts, a lcuide on said base, a movable switch men'lbcr slidablo on said guide,means for lockingr said member in extreme positions," an actuator for said inem ber, a spring connectingr said actuator and saidmember and tensioned in the same direction on both movements ot the actuator, and .means carried by the actuator tor rcleasing said lockingmeans.
2. The combination of a base provided with stationary contacts, a `guide on said base, a movable switch member slidablc on saidv'gude, means for locking said member 1n eXtreme positions`I an actuator slidable on said guide, a. spring connecting' said actuator and said member and tcnsioncd in the same direction on both movements of said actuator, and means carried by said actuator for releasing said locking means.
3. In a snap switch, the combination ol a guide,.a movable switch member slidable thereonfa double-ended latch to lock said member in extreme positions,v an actuator havingmeans for trippingsaid latch, and a springr connecting said actuator and said member and tensioned in the same direction on both movements of said, actuator.
il. In al snap switch, the combination of a Aefuide, a movable switch member slidable thereon, a double-ended latch pivoted on said guide and operating to hold said member in extreme positions, an actuator for said move able member provided with latch trippinpr means, and a spring connectingsaid actuator and said member and tensioned in the same direction on both movements of said actuator.
5. ln a snap switch, the combination of a guide, a movable switch member mounted to slide thereon, means for locking said member in extreme positions, an actuator mounted to slide on said guide, and spring connected rods bearing upon opposite sides oi the switch member and adapted to be drawn apart by the actuator to put the spring; connection under tension and thereafter rel use the lockingl means.
