Abstract
Abstract A compact electric switch for controlling an electric motor, with the switch including a sectional, removable module member having various of the switch circuit components thereon and therein, with the module member being adapted to be received in a housing member and retained therein in coacting relation with respect to movable electrical contacts in the upper portion of the housing member, which movable contacts are adapted for actuation or movement by an operator, such as for instance, a finger actuated trigger. Projecting means are provided on one of the members for coaction with means on the other member for accurately locating the module member in the housing and with respect to the movable electrical contacts thereof. The purpose is to accurately and expeditiously position the module member of the switch interiorly of and with respect to the housing member of the switch assembly.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
78 words
In a compact electronic switch for controlling an electric power unit comprising, a housing member, a switch module member received in said housing member, and means on said module member coacting with means on said housing member for positioning said module member in predetermined location with respect to said housing member, said means including projecting means comprising a laterally extending cam surface on said module member received in gripped relation between projecting finger means on said housing member.
Claim 2
Dependent Claim
78 words
In a compact electronic switch for controlling an electric power unit comprising, a housing member, a switch module member received in said housing member, and means on said module member coacting with means on said housing member for positioning said module member in predetermined location with respect to said housing member, said means including projecting means comprising a laterally extending cam surface on said module member received in gripped relation between projecting finger means on said housing member.
Claim 3
Dependent Claim
33 words
A switch in accordance with claim 1 wherein said projecting means comprises a laterally extending cam surface on said module member received in gripped relation between projecting finger means on said housing member.
Claim 4
Dependent Claim
55 words
A switch in accordance with claim 1 wherein said module member is of sectional construction for mounting switch circuit components therein and thereon and which when in assembled relationship forms a compact module member received in a chamber of said housing member, and which is located therein by said projecting means and said complementary means.
Claim 5
Dependent Claim
35 words
A switch module in accordance with claim 3 wherein at least one section of said module member is formed of ceramic material, certain of said circuit components being printed conductors on said one ceramic section.
Claim 6
Dependent Claim
68 words
A switch in accordance with claim 3 wherein each of said module sections are of a generally polygonal shaped configuration in side elevation, each said section having an inner side surface and an outer side surface, said inner side surfaces adapted for confronting relation in the assembled condition of said module sections, projecting means being located on said module member on said outer side surface of each section.
Claim 7
Dependent Claim
43 words
A switch in accordance with claim 1 including movable electrical contact means mounted in said housing member in coacting relation relative to said module member, said projecting means being adapted for coaction with said contact means for causing predetermined positioning of the latter.
Claim 8
Dependent Claim
52 words
A switch in accordance with claim 6 including actuator means operably coupled to said movable contact means for causing movement of the latter relative to said module member, said module member having stationary contact means mounted thereon adapted for coaction with said movable contact means for controlling operation of the power unit.
Claim 9
Dependent Claim
70 words
A switch in accordance with claim 6 wherin said projecting means includes a cam surface for camming coaction with said electrical contact means, said surface including an area for contact with said contact means and another area disposed laterally of the first mentioned area, said other area being received in the complementary means on the other of the members for positioning the module member with respect to the housing member.
Claim 10
Dependent Claim
19 words
A switch in accordance with claim 8 wherein said surface is of generally convex configuration in transverse cross section.
Claim 11
Dependent Claim
35 words
A switch in accordance with claim 8 wherein said complementary means comprises a pair of spaced generally resilient fingers on said other member receiving therebetween in gripped relation said other area of said projecting means.
Claim 12
Dependent Claim
158 words
A switch in accordance with claim 3 wherein said module member includes at least two spaced groups of stationary contacts mounted thereon, a bridging electrical contact member, associated with and movable with respect to each group of said stationary contacts, and from an off position wherein at least one of the bridging contact members is spaced from at least one of the stationary contacts of its associated group of stationary contacts to an on position wherein the bridging contact member engages two contacts of its associated group of stationary contacts in electrical conducting relation, each of said bridging contact members being adapted for connection to a respective conducting line from a source of electrical energy, for opening and closing the conducting line upon predetermined movement of the bridging contact member with respect to its group of stationary contacts, said projecting means coacting in camming relation with the associated bridging contact member in the off position of the switch.
Claim 13
Dependent Claim
45 words
A switch in accordance with claim 11 wherein said projecting means comprises a generally convex cam surface integrally formed on each respective module section generally centrally thereof in a direction lengthwise thereof and projects above the stationary contacts of the associated group of stationary contacts.
Claim 14
Dependent Claim
162 words
A switch in accordance with claim 1 wherein said module member comprises a pair of inter-fitting, separable module sections, one of said sections being formed of ceramic material, the other of said sections being formed of plastic material, each of said sections mounting a group of stationary electrical contacts thereon, a bridging electrically conducting member coacting with each group of stationary contacts, cam means formed on each section adapted for coaction with the associated bridging contact member in the off position of the switch for maintaining the bridging member out of contact with a predetermined one of the stationary contacts of the respective group, and means coacting with the cam means on the housing member for aligning the module member with respect to the housing member, the last mentioned coacting means comprising spaced projections on the respective side of the housing member in the interior thereof, and coacting with the lateral extremity of the respective cam means on the respective module section.
Claim 15
Dependent Claim
32 words
A switch in accordance with claim 13 wherein said spaced projections comprise resilient fingers formed integrally with said housing member and extending downwardly for coaction with the respective upwardly facing cam means.
