Abstract
The utility model discloses an error locking preventing gear for the press interlock combined switch, comprising a plurality of button switches. Every button switch comprises a shell, a push rod, and a keystroke spring. The keystroke spring is penetrated in the push rod above the shell. The shells of contiguous button switches are symmetrically equipped with connecting holes. Connecting rods are equipped between contiguous connecting holes. The corresponding sites of the push rods are equipped with slopes which are matched with the connecting rods. The length of every connecting rod is greater than the space between two push rods. This error locking preventing gear for the press interlock combined switch is convenient to be operated, that the contiguous switches are pressed in simultaneously can be prevented effectively, and the invalidation of circuit switching is avoided.
Description
Technical field
The utility model relates to a kind of button interlocking unit switch, the anti-error lock construction of particularly a kind of button interlocking unit switch.
Background technology
Used little many gears of spacing button interlocking unit switch on the circuit is because the gap ratio between each switch gear is less; therefore regular meeting takes place adjacent button simultaneously by advancing locking in operation; circuit conversion was lost efficacy, cause the inconvenience in the use.
The utility model content
At the shortcoming that above-mentioned prior art exists, the purpose of this utility model is to provide a kind of adjacent switch of stopping simultaneously by advancing the anti-error lock construction of button interlocking unit switch of handled easily.
The technical solution adopted in the utility model is: the anti-error lock construction of a kind of button interlocking unit switch, comprise several push-button switches, each push-button switch comprises housing, push rod, by key spring, be located in by key spring on the push rod of housing top, symmetry offers connecting hole on the housing of adjacent push-button switch, be provided with connecting rod between adjacent connecting hole, be provided with the slope of matching with this connecting rod at the corresponding site of push rod, the length of described connecting rod is greater than the spacing of two push rods.
The centre of described connecting rod can be provided with boss.
The anti-error lock construction of button interlocking unit switch of the present utility model, owing between adjacent push-button switch, be provided with connecting rod, on the slope that the corresponding site setting of push rod cooperates with connecting rod, when the single push-button switch of proper operation, operated push rod moves downward, the position, slope that is operated push rod makes link end parallel mobile, the other end enters the bottom, slope of adjacent buttons switch push rod, the interlocking action that is operated push-button switch is finished, if and press adjacent two push-button switches simultaneously, connecting rod can not translation, and push rod can not continue downward propelling, locking when then effectively preventing two push rods.
The utility model is described in further detail below in conjunction with drawings and the specific embodiments.
