    Abstract: A structure for supporting the electromagnet in an electromagnetically operated switch. The structure includes a metal shock plate which provides a mounting for the electromagnet and in turn is mounted on four posts that extend from a surface of the base of the switch whereon the stationary contacts of the switch are mounted. The shock plate provides a mounting for a molded part which encloses the switch contacts so that part is spaced from the base. Thus easy access to the contacts is obtained when the shock plate is removed from its position on the four posts and the shock generated by the energization of the electromagnet is transmitted through the four posts to the base when the shock plate is mounted on the four posts.

    Abstract: A contactor construction which will permit easy access to the movable and stationary contacts and replacement of the magnet coil of the contactor while the contactor is wired on a panel. The construction includes a readily detachable cover which resiliently positions the coil so the coil may be lifted from its position on a stationary magnet when the cover is removed and absorbs shock generated when resilient pads carried on the armature engage the cover when the contactor is deenergized.

    Abstract: A pilot light attachment which may be installed on an electric switch without tools. The attachment is particularly suited for use with a manually operated motor-starter-type switch and includes a pair of springlike members that supply the force for maintaining the switch and attachment assembled and an electric connection between the switch and attachment. The portion of the attachment supporting the bulb is connected to the switch by a three-point suspension which spaces the attachment from the current-carrying parts of the switch to provide the switch current-carrying parts with a maximum convective cooling.

    Abstract: An inexpensive mechanical interlock for two switches that are mounted on a common support plate. The interlock consists of a single member which is mounted in a space between the two switches when the switches are mounted adjacent to each other on the support plate. The member has a pair of bearing portions received in recesses in the adjacent walls of the switches and a pair of actuating portions that are engaged by inclined surfaces on portions of the movable contact carriers of the two switches to prevent a concomitant operation of the switches to a circuit closing position.

    Abstract: A manually operated switch having a toggle lever actuating mechanism and a locking member which will prevent actuation of the switch when the member is held in a locking position by a padlock. The locking member is arranged to move the toggle levers and a start button of the switch to an OFF operating position when the locking member is moved to the locking position and to be moved to an inoperative position when the start button and the toggle levers are moved to the ON operating position.
