Abstract: A pushbutton, momentary ON switch has a body including a barrel with longitudinally extending internal splines and ways between the splines. A plunger has radially extending lugs in the ways and is longitudinally movable in the barrel. A plurality of longitudinally extending camming teeth on the plunger engage a plurality of longitudinally extending camming teeth on a rotatable ratchet coaxial with the plunger. The ratchet is spring loaded against the plunger. The ratchet has radially extending dogs which fit into the ways when the plunger is retracted and come out of the ends of the ways when the plunger is advanced. A rotatable electrical contact cup connected to the ratchet and electrically connected to an external lead makes or breaks contact with a fixed electrical terminal in the body. The plunger teeth include a leading ramp face and a trailing ramp face wherein the leading ramp face extends a greater distance in the circumferential direction than the trailing ramp face.

Abstract: An alternate action mechanism includes a ratchet cam moving a resilient contact between first and second positions. A push button, including an interface member, rotates the ratchet cam by applying force to ratchet teeth. The alternate action mechanism includes a frame supporting the ratchet cam and aligning the ratchet portion with the interface member. In one embodiment, the ratchet portion is between two cam portions. When the ratchet cam is rotated, the cam portions moves the resilient member to one of two alternating positions. In another embodiment, the cam portion is positioned between two ratchet portions. The frame includes cam support arms receiving the ratchet cam. The frame also includes detents which prevent improper movement of the ratchet cam and provide audible indication of actuation of the mechanism. The interface member can comprise a finger to contact a ratchet tooth and rotate the ratchet cam. The finger can be U-shaped, with the edges on the open side contacting the ratchet teeth.

Abstract: In a push button switch with a star wheel having segments with trip cams and being supported in the push button so as to be rotatable about an axis which is normal to the operating direction of the push button, the star wheel is rotated, when the push button is actuated, by an unlatching structure formed on a rotation latch disposed adjacent the star wheel and engaging a projection on the star wheel. The trip cam wheel has cams which operate contact springs disposed adjacent the star wheel along the path of actuating movement of the star wheel whereby contacts are closed or opened depending on the angular position of the cams. Upon release of the push button, the push button is returned by return elements to its original position while the star wheel slides along the contact springs without operating the contacts.

Abstract: A pushbutton switch which permits partial actuation without a change of state, including a body, a cover and a contact cup having a plurality of tabs, the cup rotatably mounted on the cover. A plunger and ratchet mechanism mounted in the body incrementally rotate the contact cup and tabs upon successive actuations of the switch. A first terminal mounted on the cover is interruptibly in contact with one of the tabs as they are rotated by operation of the ratchet mechanism, while a second terminal mounted on the cover maintains electrical contact with the contact cup. A plurality of camming ramps formed in the cover are in intermittent communication with the tabs, first lifting them above a planar portion of the first terminal, then permitting one of them to come to rest on the planar portion of the terminal completing an electrical circuit between the first and second terminals. In another embodiment, a third terminal is mounted on the cover in a coplanar spaced apart relationship with the first terminal.

Abstract: An electrical switch which has a body, a contact base at one end of the body, a cam member positioned for rotation within the body, and a plunger positioned within the body for nonrotating movement. The cam member has a conductive bridge contact portion and has cam followers which engage the cam surface in the base to move the cam member between a make position in which the bridge is in contact with contacts on the base and a break position in which the bridge is spaced from the contacts on the base. The plunger has an actuatable pushbutton portion extending from the body and has driving portions which engage driven portions on the cam member to rotate the cam member upon nonrotating movement of the plunger. The plunger engages the cam member to provide a rotating first camming action, while the cam member engages the base to provide a nonrotating second camming action.
