Description
Background
The slide switch assembly of the invention finds particular utility in complex electrical and electronic systems, such as telephone answering systems, in which a large number of switching contacts are to be operated as the switch is moved from one position to another, and in which it is imperative that only one set of contacts be operated at any one time. The selector switch assembly of the invention is ideal for such uses since it is economical in its construction, since it requires a minimum of space, and since it is inherently mechanically interlocked because the actuator is capable of actuating only one of the switches at any one time as the slider is moved from one position to the next.
Although the embodiments to be described incorporate switches to be successively actuated by the actuator, it will become apparent as the description proceeds, that the switches may be replaced by other electrical elements, such as potentiometers and the like.

Detailed Description of the Illustrated Embodiment
The selector switch assembly of FIG. 1 includes a plurality of pushbutton switches designated 10, 12, 14, and 16, which are mounted in side-by-side relationship on a base 19. Each of the pushbutton switches includes a movable member designated 10A, 12A, 14A and 16A, and each movable member is reciprocally movable along a rectilinear path between a first position and a second position to actuate the corresponding switch. Each of the movable members is spring-biased to the first position by springs 10B, 12B, 14B and 16B.
A slide bracket 30 is mounted on base 19 in transverse relationship with the various pushbutton switches 10, 12, 14 and 16 and is held in place by screws 18. A slide 32 is mounted in the slide bracket 30 for reciprocal movement along a rectilinear path transversing the paths of the movable members of the various pushbutton switches. An actuator 34 is mounted on the slide 32, and the actuator successively engages the movable members of the pushbutton switches, as the slide is moved from one position to the next. As the actuator engages each movable member, it causes the movable member to move against its spring-bias from its first position to its second position, thereby actuating the corresponding pushbutton switch.
The pushbutton switches may be the multi-contact type, such as described, for example, in U.S. Pat. No. 4,100,384. The slide bracket 30 may conveniently be formed as a metal extrusion, and the slide 32 and actuator 34 may be formed of appropriate plastic. The slide 32 is provided with a handle 32A to permit manual operation of the slide for successive actuation of the switches.
In the embodiment of FIGS. 3-10, the pushbutton switches of the embodiment of FIGS. 1 and 2 are replaced by multi-contact slide switches 50, 52, 54, 56, 58 and 60; the switches being mounted on a base 62. The switches have respective switching elements 50A, 52A, 54A, 56A, 58A and 60A, each of which is movable laterally between a first and a second position to operate the individual switches.
An elongated, open-ended housing 64 is mounted on base 62 by screws 66. A slide switch actuator 68 is mounted in housing 64 and is reciprocally movable in the housing by means of a handle 70.
A channel 72 is formed on the underside of actuator 68, and the switching elements 50A, 52A, 54A, 56A and 60A all extend into the channel. Channel 72 has a laterally displaced portion 72A, and when the actuator is moved back and forth in housing 64, the switch elements 50A, 52A, 54A, 56A and 60A are successively moved between first and second positions by the displaced channel portion 72A.
It will be appreciated that the invention provides a simple and economical slide selector switch assembly which is inherently interlocked and which operates successively to actuate a plurality of switches, each of which may be of the multi-contact type.
The assembly is extremely flexible, since more or less switches may be incorporated into the assembly, depending upon the particular application.
While particular embodiments of the invention have been shown and described, modifications may be made. It is intended in the claims to cover all modifications which come within the spirit and scope of the invention.
