| 摘要 | A switch structure including a pair of electrical switches that are arranged so that when one of the pair of switches is closed the other is open. Each of the pair of switches has an actuator for changing the electrical state of the switch. The actuators are displaced in unison by a bridge member that bridges across the actuators. The pair of electrical switches and the bridge member are disposed within an inner housing. The inner housing is enclosed within an outer housing that has a mounting flange coextensive with an exterior surface thereof. An operating pin is insertable through the inner housing and the outer housing through aligned holes so that when the operating pin is inserted, the bridge member and the actuators are displaced causing a change of the electrical state of each of the pair of switches. The operating pin has a ring on an enlarged portion of one end thereof for providing ease of access. | ||||||
| 权利要求 | 1. A switch comprising an outer housing and an inner housing disposed within the outer housing; said housings being formed with aligned bores of size to accommodate insertion of a key through both bores; a reciprocally movable member in the inner housing movable from a first position in line with said bores to a second position out of alignment with them; means for biasing said reciprocally movable member to said first position; a switch responsive to movement of said reciprocally movable member from between said first and second positions to change its state; and a key of size to fit within said aligned bores and of size to force said reciprocally movable member from first to second position; said inner container comprising spaced side walls, said switch being disposed between them; and said reciprocally movable member comprising a pair of spaced side walls joined by an end wall movable between said first and second positions; one of said pair of side walls of the inner housing and reciprocally movable member being mounted astride the other. 2. The invention defined in claim 1 in which said inner container is provided with a lower side wall and is open at the side opposite, and in which the side walls of the reciprocally movable member are bridged by an upper side wall. 3. The invention defined in claim 1 in which said inner container is resiliently mounted upon said outer container. 4. The invention defined in claim 3 in which said switch comprises two switches having individual reciprocally movable actuators mounted to be engaged and reciprocally moved as an incident to movement of said reciprocally movable member. 5. The invention defined in claim 4 in which said outer housing comprises a flange extending in a plane parallel to the axis of said bores; and in which said key comprises a shaft and a holding ring pivotally mounted on thE shaft and of size exceeding the separation of the axis of the shaft and said flange. |
