Abstract: An electrical switch has a snap action blade with a contact pad. The snap action blade toggles between a first configuration at which the contact pad abuts a stationary contact and a second configuration at which the contact pad is remote from the stationary contact. An actuator moves the snap action blade between the first and second configurations. A reset spring has a first position which biases the movable contact into one of the first and second configurations, and has a second position at which that biasing does not occur. A reset selector acts to determine whether the reset spring is in the first or second position. A manual reset actuator is provided to move the snap action blade into the one of the first and second configurations when the reset spring is in the second position. Operation of the reset selector selects whether the switch is in an automatic reset mode or a manual reset mode.

Abstract: AN ELECTRICAL CIRCUIT OVERLOAD PROTECTIVE DEVICE OF THE THERMALLY RESPONSIVE BIMETAL TYPE WHICH CAN BE SELECTIVELY SET FOR EITHER AUTOMATIC OR MANUAL RESET MODES OF OPERATION. OVERLOAD RESPONSIVE UNITS, FOR ONE OR MORE CIRCUIT BRANCHES EMPLOYING STACKS OF BIMETAL DISCS AS THERMALLY RESPONSIVE ELEMENTS, AND ARE MOUNTED WITHIN A HOUSING ON A COMMON BASE. EACH OVERLOAD UNIT HAS AN INDIVIDUAL SNAP ACTING SWITCH WHICH OPENS IN RESPONSE TO AN OVERLOAD CONDITION AS DETECTED BY THE HEAT DEVELOPED IN A HEATER COIL CONNECTED IN THE BRANCH CIRCUIT WHICH SURROUNDS IT THERMALLY RESPONSIVE ELEMENT. THE SWITCHES OF THE OVERLOAD UNITS ARE ALL CONNECTED IN A SINGLE SERIES CIRCUIT BETWEEN TERMINALS PROVIDED FOR CONNECTION TO A CIRCUIT TO BE CONTROLLED. IN A MANUAL TRIP-FREE MODE OF OPERATION A PUSHBUTTON LEVER UPON SUBSIDENCE OF ALL OVERLOAD CONDITIONS IS DEPRESSED INWARDLY OF THE HOUSING TO AFFORD MANUAL RESET OF THE MOVABLE CONTACT MEMBERS OF ANY SWITCH TRIPPED OPEN BY OVERLOAD RESPONSE. ALTERNATELY THE RESET LEVER MAY BE LATCHED IN SUCH DEPRESSED POSITION WHEREIN THE CONTACT OPENING MOVEMENT OF THE MOVABLE SWITCH CONTACT MEMBERS IS SO LIMITED THAT THEY WILL IN DIVIDUALLY AUTOMATICALLY RESET UPON SUBSIDENCE OF THE OVERLOAD CONDITION IN THEIR RESPECTIVE BRANCH CIRCUITS. A MODIFIED FORM OF AMBIENT TEMPERATURE COMPENSATED BIMETALLIC DISC TYPE OF OVERLOAD RESPONSIVE UNIT IS PROVIDED FOR USE WHEREIN THE DEVICE WILL BE SUBJECTED TO HIGH OR WIDELY VARYING AMBIENT TEMPERATURE CONDITIONS.

Abstract: An interlock is presented which may be mechanically interconnected with a circuit breaker. The interlock toggles between a locked out position that causes the circuit breaker to trip and prevents closure thereof and a non-locked out position wherein the circuit breaker functions. The interlock includes a frame, a lockout actuator supported by the frame, a reset actuator also supported by the frame and a latching assembly. The latching assembly includes a lockout lever that is responsive to movement of the lockout actuator that is pivotably supported by the frame and a lockout trip rod responsive to movement of the lockout actuator. Also provided is a reset lever that is responsive to movement of the reset actuator and that is also pivotably supported by the frame. The reset lever is configured to prevent movement of the lockout actuator without movement of the reset lever and wherein the lockout trip rod is configured for movement between a locked out position and a non-locked out position.
