摘要： The sealed toggle action switch comprises an operating lever having a front operating arm projecting out of the front component of the casing. The lever has a rear arm, projecting into the casing and carrying a contactor plate for relative sliding and swinging movement. A coil spring is received around the rear arm and is compressed between the contactor plate and the front sealing flange of a soft resilient sealing boot, such sealing flange being compressed against the operating lever. The boot has a rear, outwardly projecting sealing flange which is retained between the front and rear casing components. The contactor plate has a pair of J-shaped flanges which are slidably engageable with first and second fixed contacts having forwardly projecting protuberances, affording a detent action with the J-shaped flanges. In one position of the operating lever, the J-shaped flanges of the contactor plate engage both of the first and second contacts. In the second position of the operating lever, one of the J-shaped flanges is held out of engagement with the second contact by a pair of insulating ramps on the rear casing component. The first fixed contact preferably comprises a contact plate having forwardly projecting contact flanges affording protuberances or humps, over which one of the J-shaped flanges is movable when the contactor plate is moved between its first and second positions. In one position of the operating lever, the front operating arm is adapted to retain the end fitting of a safety lanyard. In this position, the front arm engages tabs which assist in retaining the end fitting of the lanyard.

摘要： The switch comprises a hollow, generally rectangular casing, a generally rectangular pushbutton slidable rearwardly in such casing, and a terminal supporting block closing the rear end of such casing. All of such components are made of moldable resinous plastic materials. The block carries forwardly projecting contact points which connect with external electrical terminals. The pushbutton carries a cup-shaped contactor, slidably and rotatably mounted on a retaining pin which is pressed into a hollow post projecting rearwardly from the pushbutton. A compression coil spring is mounted around the pin and the post, between the contactor and the pushbutton. The contactor is fitted with an axial eyelet on which the contactor is freely rotatable. The contactor is movable into wiping engagement with the contact points, when the pushbutton is pushed rearwardly against the biasing force of a coil spring, compressed between the pushbutton and the terminal supporting block. The casing has a pair of latching fingers with latching teeth which are slidable along guide grooves in the block. The latching teeth are spread apart by outward flexure of the latching fingers, until the latching teeth snap into latching recesses at the rear end of the grooves. The casing also has a pair of locating fingers, projecting rearwardly in a rectangular relationship with the latching fingers, and receivable in locating channels formed in the terminal supporting block. The casing and the block are easily assembled by pushing them together until the latching teeth snap into the latching recesses.

摘要： The switch has at least one contact plate, mounted on the inner side of an insulating wall forming one side of a casing. The contact plate has a contact rail or some other contact element which is engageable by a contactor on a movable carriage within the casing. The contact plate has a mounting hole surrounded by a circular flange extruded from or otherwise formed in one piece with the contact plate. A terminal bar is mounted against the outer side of the insulating wall and is connected to the contact plate by a terminal rivet, extending through the circular flange with an interference fit to establish good electrical contact therewith. The rivet also extends through an opening in the insulating wall and a mounting hole in the terminal bar. The swaging of the rivet causes the shank of the rivet to bulge outwardly, thereby expanding the circular flange and establishing a heavy interference fit between the flange and the swaged rivet, to establish and maintain low-resistance electrical contact between the flange and the rivet. Initially, the flange is preferably tapered, but is expanded by the bulging of the swaged rivet. The bulging of the swaged rivet also preferably establishes an interference fit between the rivet and the mounting hole in the terminal bar, to assure low-resistance electrical contact between the rivet and the terminal bar.

摘要翻译： 开关具有至少一个接触板，安装在形成壳体一侧的绝缘壁的内侧上。 接触板具有接触导轨或一些其它接触元件，其可通过壳体内的可移动滑架上的接触器接合。 接触板具有由与接触板一体地挤出或以其它方式形成的圆形凸缘包围的安装孔。 端子排安装在绝缘壁的外侧，并且通过端子铆钉连接到接触板，通过过盈配合延伸穿过圆形凸缘以与其形成良好的电接触。 铆钉还延伸穿过绝缘壁中的开口和端子条中的安装孔。 铆钉的型锻使铆钉的柄部向外凸出，从而使圆形凸缘膨胀，并在法兰和铆接铆钉之间建立了一个沉重的过盈配合，以建立和保持法兰和铆钉之间的低电阻电接触。 最初，凸缘优选是锥形的，但是通过模锻的铆钉的膨胀而膨胀。 铆钉铆钉的凸起也优选地在铆钉和端子条中的安装孔之间形成过盈配合，以确保铆钉和端子条之间的低电阻电接触。

摘要： A boot seal assembly for external movable members such as switch actuators. The assembly includes a cooperating structural support that provides a guide for the movable member as well as a retaining seat for a fixed portion of the boot seal. The movable member provides a retaining means for the remaining collapsible portion of the boot seal without affecting the direction of travel or required operating force for the movable member.
