International Classification:

H01H 1908

US Classification:

200 11DA

Abstract:

A rotary switch includes a stator, rotor and shaft for the rotor. The stator has a complex conductive matrix formed of criss-crossing conductive sections integrally joined together and integral with a central annular ring. The annular ring in turn has radially inwardly-extending switch sections. There is a non-conductive support member for the matrix, with the matrix and support member having respective and cooperating openings and projections for positioning the matrix on the support member. The rotor has a plurality of pockets with contact members positioned in at least one of the pockets and arranged for electrical contact with portions of said matrix.

Cherry Electrical Products Corp. - Waukegan IL

International Classification:

H01H 160
H01H 120

US Classification:

200242

Abstract:

A panel mounted switch consisting of two complementary side sections housing the switch components that include a plunger-type actuator carrying two movable switch blades and a series of fixed terminals. The switch blades being yieldably connected to the actuator whereby they are free to rock about their longitudinal axis upon engagement with certain of said fixed terminals, thereby achieving a self-cleaning, wiping switching contact.

International Classification:

A63B 5304
A63B 5306

US Classification:

273170

Abstract:

An improved golf club with controllable dynamic characteristics is provided with a weighting chamber of controllable weight rigidly secured within an elongated cavity defined through the head of the golf club. The chamber is dynamically weighted by providing a volume of liquid-like material such as mercury within it and has an elongated cavity defined through the cross-section of the club head. The cavity consists of a pair of interconnected cylindrical sections and is provided with a threaded set screw located in the rearward cylindrical section for varying the internal volume of the chamber so as to provide variation in its volume as well as the available displacement area for the material contained in it. The weighting chamber, when filled with the appropriate volume of material, functions to increase the head weight by a predetermined amount. When the golf club is swung downwards from the top of its back swing, the movement of the liquid-like material within the weighting chamber in the direction of swing provides added momentum which produces increased force of impact at the point where driving contact is made between the face of the club and the ball.

International Classification:

H01H 1914

US Classification:

200155R

Abstract:

A rotary switch construction wherein a stator has a pocket for receiving a rotor. The rotor has a flexible rim which permits it to snap-fit into the pocket of the stator. A plurality of angled surfaces on the stator compress the rotor rim as it is inserted into the pocket of the stator. Retainer means are provided to hold the rotor in the stator. The rotor further includes a plurality of stop pairs. The stator has a single, fixed stop which is disposed between the stops of one of the pairs on the rotor. The rotor stops have variable arcuate spacing so that, depending on which pair of stops spans the fixed stop, the degree of rotational freedom of the rotor can be selected. In another aspect, the rotary switch includes means on the rotor for fastening the rotor blade in place.

Inventors:

Raymond Lewandowski - Mount Prospect IL

Assignee:

Cherry Electrical Products Corporation - Waukegan IL

International Classification:

H01H 1348

US Classification:

200 67DB

Abstract:

A tactile feedback switch having a contactor element having a curvilinear portion which temporarily changes from a substantially convex shape to a substantially concave shape upon movement of the contactor element into engagement with an electrical contact. An indentation in the contactor element reduces the force otherwise needed to be applied to the top portion of the contactor element in order to maintain the contactor element in engagement with the electrical contact.

Assignee:

Cherry Electrical Products Corporation - Waukegan IL

International Classification:

H01H 900
H01H 316

US Classification:

200 50A

Abstract:

An interlock switch used with an electrical appliance such as a microwave oven. The interlock switch includes a cantilevered common switch element, and two other switch elements mounted on opposite sides of the common switch elements. When the appliance door is closed, the common switch element makes contact with the switch elements on one side and breaks contact with the switch element on the other side.
