A surface mount snap switch and method of making the same, including a housing having a plurality of channels formed therein and a cover configured for snap-fit engagement with the housing. The snap switch also includes an actuator slidably disposed at least partially within the housing, a first terminal having an external surface mount portion and another portion press-fittingly held within one of the plurality of channels of the housing, and a second terminal having an external surface mount portion and another portion press-fittingly held within another one of the plurality of channels of the housing. The snap switch further includes a blade contact having a first end portion pivotally associated with the first terminal and a second end portion comprising a blade contact button, and the actuator is configured to interact with the blade contact to electrically couple the first terminal and the second terminal.

A switch includes a pushbutton comprising an actuating portion, a first fixed contact element and a first movable contact element facing the first fixed contact element for establishing a first switching way. The first movable contact element may include a movable portion of a first elastically deformable conductive blade. The actuating portion may include a first cam which cooperates with a cam follower portion of the first blade to deform or relax the first blade for longitudinally moving the first movable contact element to come into contact, or out of contact, with the portion of the first fixed contact element, depending on the vertical position of the actuation member. A second fixed contact element and second movable contact may be similarly constructed to provide a second switching way.

Electrical pushbutton switch

A toggle switch includes a hollow base, a switch mechanism, a cover, a bushing extending from the cover, a toggle lever, and a one piece resilient sealing component. The sealing component includes a lever seal surrounding the toggle lever and covering the inner wall of the bushing for sealing a space between the toggle lever and the bushing. A cover seal forms a lower closed sealing ring compressed between the cover and the base for sealing the cover to the base. The one piece resilient sealing component also includes an upper closed sealing ring surrounding the bushing and extending on a portion of the upper surface of the cover for cooperating with a panel for mounting the switch.

A low cost miniature illuminated pushbutton switchfor soldering to a circuit board (), which avoids damage to an LED during such soldering to the board. The pushbutton assembly, which slides between outward and inward positions, includes a molded plastic frame (), sheet metal pushbutton conductors () mounted on the frame, and an LED () having a bulb () lying forward of the frame and having leads () joined to front ends of two of the pushbutton conductors. The pushbutton assembly also has a pushbutton depressing element () with a through passage () that surrounds the bulb and extends forward of the bulb, the pushbutton element having an inward end () that joins to the pushbutton frame through lugs (). A pair of the sheet metal conductors () have inward ends exposed to deflectable housing contact portions (), the sheet metal conductors have middle portions that extend through the frame, and the sheet metal conductors have outer ends forming crimp barrels () that are crimped to the leads.

A switchlock assembly with snap-in cam for mounting in a panel from the front with the panel cutout being smaller than the cam radius. The switchlock assembly comprises a switch base, a shell, a plug operable by a key, the cam and a latch clip. The latch clip prevents the plug from being removed from the shell. The latch clip also secures the cam within the plug and prevents the cam from being removed, but does not prevent the cam from rotating when a key is inserted into the plug of the switchlock assembly and turned. Switch tumblers and tumbler splines enable a key to be pulled out in a designated position, but not to allow the key to be pulled out 180 degrees from the designated key pull position.

A dual tactile feedback, three-state, low profile pushbutton switch comprising an insulated housing, a metal dome, an extended travel molded elastomeric dome or stem having a conductive material on a bottom surface for contacting the metal dome and contacts in the switch housing, a collar having an opening for a top portion of said elastomeric dome to protrude therethrough, and a fixed contact under the metal dome on the base of the insulated housing connected to a switch terminal. A flat plate with four legs is placed above the stem which moves adjacent to the walls of the housing. The plate extends through a frame and openings on the sides of the frame snap on to the sides of the insulated housing. Greater switch reliability is achieved by having the elastomeric dome with a bottom portion comprising a conductive material for contacting the metal dome. An alternate embodiment of the three-state switch comprises a pushbutton disposed above an upper, extruded, elastomeric element for lower cost advantages having conductive material on a bottom surface for making electrical contact within the base of the switch housing and a lower metal dome, when the pushbutton is activated. The lower metal dome also makes electrical contact with contacts in the base of the switch housing.
