It is also plain that the lmob 16 can be rotated to close the circuit through either post 4 or 5 without closing either circuit through posts 2 and 3, or hat after the circuit through either post t or is completed then the post l0 may be tilted either way and a circuit completed through either post 2 or 3.

2. In a multiple contact switch, a plurality of contacts, a tiltable post connected to a source of current supply, contacts on said post, means to hold said contacts normally out of contact with said tirst named contacts, and means to close one or more of said contacts.

3. In a multiple contact switch, a plurality of contacts, a rotatable and tiltable post connected to a source of current supply, contacts on said post, means to hold said contacts normally out of contact with the first named contacts, and means to closecone or more ot said contacts.

ll. In a multiple contact switch, a base plate, a plurality of contacts, a post connected to a source of current supply, contacts on said post, means to hold said contacts normally out of contact with the iirst named contacts, kand means to close one or more of said contacts.

5. In a multiple contact switch, a base plate, a plurality of posts on said base plate, a plu rality of contacts in said posts, a rotatable and tiltable postconnected to a source of current supply, contacts on said post and an arm on said post, contacts on said arm,`means to hold said contacts normally out of contact with the rst named contacts, and means to close one or more ott said contacts.

6. In a multiple contact switch, a base plate, a plurality of posts mounted thereon, adjustable contacts mounted in said posts,

^ means to connect electrical conductors to said posts, a rotatable and tiltable post, contact-s on said post adapted to engage certain ot the said first named contacts when the post is tilted, an armon said post, contacts on said arm adapted to engage certain of said contacts when the post is rotated, and a spring which holds said contacts on said rotatable and tiltable post normally out of engagement with the first named contacts.

7. In aI multiple contact switch, a base plate ot insulating material, a plurality of posts fixedly mounted thereon, a plurality of screws adjustably mounted in said posts, contacts on said screws, means to connectsaid posts to electrical conductors, a slot in said base plate intermediate two of said posts, a post mounted in said slot, a coil spring, surrounding` a portion ot said post, which holds said post normally in a Vertical position, a knob on said post, said post being connected to a source oit electrical supply, an arm which entends intermediate two ot' said first named posts, contacts-on said arm which engage the contacts on the screws when the post is rotated, and springs which hold the contacts on the arm normally out of contact with the cont-acts on the screws.

8. In a multiple contact switch, a base plate, a plurality ot' posts mounted thereon, adjustable contacts mounted in said posts, means to connect electrical conductors to said posts, a rotatable and tiltable postl` contacts on said post adapted to engage certain of said first named contacts when the post is tilted, an arm on said post, contacts on said arm adapted to engage certain of said contacts when the post is rotated, a spring which holds said contacts on said rotatable and tiltable post normally out of engagement with the iirst named contacts, and means to hold the contacts on said arm out of contact with the contacts on said posts.
