Abstract: The invention relates to a plunger operated reed relay switch module that incorporates a novel permanent magnet and mounting for the magnet which permits the plunger which operates the magnet to have the same travel characteristics as a plunger which actuates the contacts in a plunger operated snap switch. The switch module thus may be used as a replacement for a snap switch in a device when the device is required to control the input signals in a solid state logic circuit.

Abstract: In a control system for a direct current series motor, the contacts of a single throw reed relay are responsive to motor current through a winding in a motor supply conductor to selectively control the application of a motor field weakening shunt resistor by a switching circuit. The charging of a timing capacitor delays action of the switching circuit to prevent motor ''''hunting''''. The opening of the reed relay contacts under low motor load conditions permits charging of the capacitor and activating of the switching circuit to place the shunt resistor across the motor field for high speed operation. Under increased motor load, the reed relay contacts close and the capacitor discharges to time the removal of the shunt resistor from across the field. A by-pass transistor by-passes the reed relay contacts preventing activation of the switching circuit until the motor has reached its maximum unweakened field speed and the relay is provided with shunt windings to prevent ''''chattering'''' due to wavering motor current.

Abstract: The joint structure includes a pair of joint tie channels with gaskets and a pair of joint covers with gaskets, one of the joint covers having a captive nut and the other of the joint covers having a removable closing cap for providing access to a joint bolt threaded into the captive nut. For horizontal edgewise mounting of a pair of bus duct sections, the gasket material is removed from the bottom tie channel. For horizontal flatwise mounting, the closing cap is removed from its joint cover, which is disposed at the bottom of the joint. For vertical mounting, the gasket material is removed from the lower edges of both joint covers.

Abstract: A circuit breaker is provided with a current-limiting fuse mounted in a removable fuse holder and electrically connected in series with the circuit breaker contacts. A self-biasing mechanical interlock member prevents insertion or removal of the fuse unless an operating lever is in the OFF position. An indicator lamp is connected across the fuse and circuit breaker contacts to indicate an open circuit caused either by blowing of the fuse or tripping of the circuit breaker. A switch in the energizing circuit of the lamp prevents lighting thereof when the operating lever is in the OFF position. The interlock member carries current to the lamp and serves as a movable contact for the switch.

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: The circuit breaker has a trip lever which normally is latched by a latch mechanism in an untripped position wherein it maintains the contacts in condition to be opened and closed by a manual operator. The latch mechanism releases the trip lever only upon the occurrence of abnormal current conditions whereupon the contacts are opened and the trip lever is returned to a tripped position. An indicator strip of flexible, nonconducting material having an indicating portion at its outer end is carried by the trip lever. The strip is pushed thereby endwise so that the outer end of the strip engages an interior wall of the housing of the circuit breaker and is guided therealong into alignment with a window in the wall, as the lever moves to tripped position, thereby indicating the tripped condition of the circuit breaker. The indicator strip flexes during its movement to and from trip indicating position to facilitate its proper movement.
