Definitions
- Vanderhye Attorney-Holman and Stern ABSTRACT In an electrical switch an operating member is coupled to an operating lever and is movable by the operating lever from an inoperative position to at least one operative position in which a circuit between a pair of terminals on the switch is completed.
- the operating lever is also movable in a different plane against the action of resilient means, from an inoperative position to a position it causes the same circuit to be completed. This is accomplished by using an operating member in two parts, one of which carries the switch contacts and the other of which locates relative to the switch housing, so that the part of the contact member carrying the contacts can be moved independently of the other part.
- FIG. 1 is an inverted plan view of an electrical switch with the base removed
- FIG. 2 is a view similar to FIG. 1 showing the parts of the switch in an operative position other than that shown in FIG. 1 and,
- FIG. 3 is a sectional view of FIG. 2.
- the switch includes a molded insulating body 11 one side of which is open to define a compartment 12, and on the other side of which is formed an integral bearing 13.
- a molded contact member 14 having a central portion 15 in which is formed a rectangular slot, first and second arms 16,17 extending outwardly from the central portion 15 towards the outer walls of the compartment 12, the arm 16 carrying at its end a first set of resilient contacts 18, an integral bearing bush 15a extending from the central portion 15 and engaging the bearing 13, and a pair of arcuate flanges 20 extending from the central portion 15 in the opposite direction to the bearing bush and engaging arcuate portions of the body to provide a second bearing for the contact member 14.
- Each of the arms 16,17 carries a spring-loaded ball engaging a respective cam form on the wall of the body 11 so that the contact member 14 is angularly movable from a central inoperative position in opposite angular directions to first and second operative positions.
- the switch further includes an operating lever 19 secured to a rectangular insulating block 21 located within a diametrically extending slot in the bearing bush 15a by a pin 22 extending through the bush 15a and block 21. Extending integrally from the block 21 is a hollow post 23, which is located within the rectangular slot in the contact member and within which is trapped a compression spring 24.
- the post is engaged within a central hole 26 formed in a second contact member which includes a relatively short arm terminating in a lug which is pivotally engaged within a hole formed intermediate the ends of the arm 16 of the member 14, and a longer arm which at its end carries a second set of resilient contacts 27, and intermediate its ends is formed on its face engaging the second arm of the first contact member with a groove 28 containing a compression spring 29 acting between one closed end of the groove 28 and a post 31 upstanding from the arm 17 of the member 14 so as to urge the second contact member 25 into engagement with an end of one of the arcuate flanges
- the compartment 12 is closed by a base 32 which conveniently is in the form of a printed circuit board secured to the body, and the arrangement is such that when the board is in position it is engaged by the first and second sets of contacts 18, 27.
- the spring 24 trapped within the post 23 urges a ball 24a into a hole 33 in the printed circuit board 32 and together with the spring 29 in the groove 28 urges the rectangular block 21 angularly about the pin 22 to a position in which the block 21 engages a part of the body 11.
- the driver wishes to operate the wipers for a single cycle, he moves the operating lever 19 horizontal (still assuming the contact board 32 to be vertical) away from the contact board 32.
- the block 21 now moves angularly within the diametrical slot about the pin 22 and the resultant movement of the post 23 moves the ball 24a out of the hole 33 and moves the contact member 25 angularly relative to the contact member 14 about the pivot defined by said lug, this angular movement compressing the spring 29, in the groove 28.
- the angular movement of the contacts 27 completes the same circuit as when the operating lever 19 is moved clockwise to operate the wiper motor at the predetermined speed.
- the driver can release the operating lever 19, whereupon the spring 29, assisted by the spring-loaded ball 240, return the contact member 25 and operating lever 19 to their normal positions, the circuit to the motor being maintained through the self-parking switch of the motor until the end of the single wiping stroke.
- the angular movement of the rectangular block 21 is permitted by virtue of a slot 34 in the bearing 13 when the operating lever 19 and member 14 are in their central inoperative position, but is prevented in other angular positions of the member 14, by engagement of the block 21 with the bearing 13 so that the single wipe facility can be employed only when the wiper motor is off.
- the switch can if desired control other functions. For example an additional angular position of the switch could control windscreen washers, this position being allowed.
- the switch of course has other uses, and it may not always be necessary to restrict the permitted horizontal movement of the operating lever to a single angular position as in the example described.
- An electrical switch including a casing, an operating member movable angularly within the casing, an operating lever, means coupling the operating lever to the operating member so that movement of the operating lever in a first plane moves the operating member from an inoperative position to at least one operative position, a pair of terminals on the switch, between which an electrical circuit is completed in said operative position, the operating lever being movable additionally in a second plane, from an inoperative position to a position in which it causes said circuit between said pair of terminals to be completed, resilient means resisting said movement of the operating lever in said second plane, and, the operating member comprises a first part which moves angularly with the operating lever when the operating member is moved in said first plane, a second part movable with said first part during movement of the operating lever in said first plane, and so coupled to the operating lever that movement of the operating lever in said second plane moves said second part relative to said first part, said second part carrying the switch contact completing said circuit, and the switch being provided with coacting parts on the first part of the operating member
