摘要： An auxiliary switch assembly for mounting on and operation by a power contactor includes a molded plastic housing cover to be mounted on the contactor by screws which provides a space within the housing for two electrical switches, which for this assembly are standard snap-action switches, and space for a movable element mechanically connected to the actuator of the power contactor which moves within the confines of the housing cover to engage the plunger in each such switch.

摘要： An electrical switch includes a rocker-type actuator adapted to be pivoted between first and second positions within a housing in order to close and open switch contacts. The actuator slidably supports a latch which normally engages the housing to prevent the actuator from being pivoted to its switch-closed position. By pulling on the latch and then lifting on the actuator, the actuator may be pivoted to its switch-closed position; the two-step operation protecting against accidental actuation of the switch. The switch housing is mounted with a snap fit in an opening iun a panel. A lug on the housing engages the underside of the panel to prevent the switch from being pulled out of the opening in the event a heavy lifting force is applied to the actuator without first releasing the latch. One switch contact is adapted to pivot and slide on a fulcrum which is laterally offset from the pivot axis of the actuator in order to delay opening of the switch relative to the position of the actuator.

摘要： A three-position electrical switch includes a rocker-type actuator adapted to be pivoted within a housing in opposite directions from a neutral position to first and second actuated positions in order to close first and second sets of switch contacts. The actuator carries a latch which normally engages the housing to prevent the actuator from being pivoted from its neutral position to either of its switch-closed positions. By manually sliding the latch and then pivoting the actuator, the actuator may be moved to either of its switch-closed positions; the two-step operation requiring a conscious effort and protecting against accidental actuation of the switch. The actuator is frictionally maintained in both of its switch-closed positions but may be returned to its neutral or switch-open position by a simple single motion thereby enabling rapid and easy opening of the switch.

摘要： An electrical rocker switch of the type having a removable actuator key to prevent turning the switch "on" when the key is removed, such switch having a rockable carrier member for operating switching bridge structure, a rocker member mounted cooperatively with said carrier member in a switch casing and with each such two members being movable independently of the other about a common axis. The removable key couples the rocker member and carrier member so that all three are then operated together as a coupled structure by actuation of such key, said switch having contact means for two different circuits, with the key member when inserted into the carrier-rocker members in one direction accomplishing the operation of the contact means to close one of said two circuits through the switch, and with removal of the key member, rotation thereof through 180.degree. about an axis at right angles to said common axis and then reinsertion in the carrier-rocker members in that rotated position coupling said two members for actuation by the key member when it is moved in the opposite direction to close the other circuit. The key member has a portion engageable with stop means with the switch to limit the key member movement in the direction of such movement until it is stopped, having closed the selected one of said two different circuits in an "on" position in such moving. The switch cannot be operated to a different circuit "on" position with the key removed.
