US Patent:

42464544, Jan 20, 1981

Filed:

Dec 11, 1978

Appl. No.:

5/967917

Inventors:

Donald L. Ray - Oaklandon IN

Assignee:

Emhart Industries, Inc. - Indianapolis IN

International Classification:

H01H 708

US Classification:

200 38R

Abstract:

A cam is axially displaced so that a pair of cam followers sequentially drop from the cam's outer periphery to sequentially close a pair of electrical switches which are responsive to the cam followers. Upon completion of a program, the cam is permitted to displace to its original position. A coil spring clutch permits an actuator to be located in a predetermined position for axial displacement of the cam.

Assignee:

Emhart Industries, Inc. - Indianapolis IN

International Classification:

H01H 700

US Classification:

200 38B

Abstract:

An intermittent drive includes a pair of reciprocating drive pawls which individually and alternately drive a camstack in a step by step maneuver. Electrical switches open and close in response to the camstack. One of the drive pawls includes a lost motion connection between it and a rotating member. There is a sub-interval switch having a cam disposed within the intermittent drive and a cam follower which operates a switch.

Inventors:

Ellis P. Lipp - Charlottesville IN
Donald L. Ray - Oaklandon IN

Assignee:

Emhart Industries, Inc. - Indianapolis IN

International Classification:

H01H 1500

US Classification:

200 16B

Abstract:

A housing has a flat side and an open end opposite the flat side, which open end is closed by a circuit board, sandwiching a slidable contact carrier between it and the flat side. Normal power terminals are carried by the flat side and low power traces by the circuit board. Contacts carried on both sides of the carrier open and close circuits on the flat side and the circuit board as the carrier is slid in the housing. The carrier slides on a stabilizing bar with a highly finished surface, thereby smoothing out force irregularities that could be caused by the small size and differing characteristics of the two sides of the switch.

Assignee:

Emhart Industries, Inc. - Indianapolis IN

International Classification:

H01H 700

US Classification:

200 38A

Abstract:

A cam is axially displaced so that a pair of cam followers sequentially drop from the cam's outer periphery to sequentially close a pair of electrical switches which are responsive to the cam followers. Upon completion of a program, the cam is permitted to displace to its original position. A clip ring clutch is used to provide a two-way manual rotation of a ring which carries a ramp that axially indexes the cam.

Appl. No.:

7/248161

Inventors:

Donald L. Ray - Oaklandon IN
Ellis P. Lipp - Charlottesville IN

Assignee:

Emhart Industries, Inc. - Indianapolis IN

International Classification:

H01H 304

US Classification:

200 17R

Abstract:

A contact is attached to a carrier and the carrier-contact assembly encapsulated in a chamber in a light guide, the chamber having an open end closed by a circuit board having traces on it. A lever fitting into a lever housing in the carrier passes through a slot in the light guide permitting the carrier to be manually slid within the chamber parallel to the circuit board, thereby moving the contact over the traces. The carrier contacts the light guide wholly along narrow ribs which are greased with a viscous grease. An opaque cover, having a slot through which the lever extends, encloses the light guide. An opaque tape located between the cover and the light guide and having an opening through which the lever extends, slides with the lever to prevent light from escaping through the slot in the cover as the lever is moved. A rim on the lever housing prevents light from escaping around the opening in the tape.

Appl. No.:

8/024005

Inventors:

International Classification:

H01H 314

US Classification:

200 6189

Abstract:

A pedal operated switch assembly has a plunger that operates blade switches and is mounted on a brake pedal in a manner providing self-adjustment. The pedal operated switch assembly has a pivoting lever with a portion that contacts the brake pedal and a portion that contacts a plunger creating a mechanical advantage for actuating the plunger. The mechanical advantage of the pivoting lever reduces the amount of brake pedal travel necessary operate the pedal operated switch assembly.
