Further, described cantilever cam is provided with left working position projection, right working position projection.
Further again, the cross section of described main shaft is a boss.Described boss can be waist shape boss, ellipse around boss or other shaped boss.
Operation principle of the present utility model is: referring to accompanying drawing 1, a working position protrusions press pressing plate (3) of cantilever cam (5), pressing plate (3) promotes the push rod of travel switch (2), realize the connection (or disconnection) of control signal, meanwhile another working position projection of cantilever cam (5) is left pressing plate (9), and pressing plate (9) is in the state of not stressing, and travel switch (10) is by the effect of self reset force, realize the disconnection (or connection) of control signal, first power supply closes a floodgate; The cantilever of cantilever cam (5) is by pin (7) drivening rod (11) simultaneously, connecting rod (11) acts on cantilever cam (16) by pin (19), cantilever cam (16) acts on main shaft (15), the control signal of a working position of cantilever cam (16) is connected (or disconnection), the control signal of another working position disconnects (or connection), second source disconnects, thereby realization is chain with second source, prevents that effectively first power supply and second source are in "on" position simultaneously.
Referring to accompanying drawing 2, under state shown in the accompanying drawing 1, under the effect of main shaft (6), clockwise rotate at power, the disconnection of a working position control signal (or connection), meanwhile the control signal of another working position is connected (or disconnection), and first power supply disconnects; Groove on the connecting rod (11) is dodged action, and second source still is in off-state, makes first power supply and second source all be in off-state.
Referring to accompanying drawing 3, under state shown in the accompanying drawing 2, under the effect of main shaft (15), clockwise rotate at power, the disconnection of a working position control signal (or connection), meanwhile the control signal of another working position is connected (or disconnection), and second source closes a floodgate, and first power supply still is in off-state, reach chain purpose, prevent that effectively power supply 2 and power supply 1 are in "on" position simultaneously.
This programme can guarantee that the same time has only one road power supply, and the process of power supply conversion is: Fig. 1 state (first power supply closes a floodgate, second source disconnect)---Fig. 2 state (first power supply disconnects, second source disconnect)---Fig. 3 state (first power supply disconnects, second source closes a floodgate)---Fig. 2 state (first power supply disconnects, second source disconnect).
The beneficial effects of the utility model mainly show: 1, output signal accurately and reliably, chain good reliability; 2, little, the simple structure that takes up room; 3, outgoing position signal accurately is for electrical control provides the reliable position judgement; 4, can stack some groups in the travel switch installation place, be easy to the expansion of auxiliary switch.
(4) description of drawings
Fig. 1 is the view of the auxiliary switch that first power supply closes a floodgate, second source disconnects.
Fig. 2 is the view of the auxiliary switch that first power supply disconnects, second source disconnects.
Fig. 3 is the view of the auxiliary switch that first power supply disconnects, second source closes a floodgate.
(5) embodiment
Below in conjunction with accompanying drawing the utility model is further described.
With reference to Fig. 1, Fig. 2, Fig. 3, a kind of auxiliary switch of automatic transfer switching electric appliance, it comprises the main shaft (6) that can rotate that is arranged on the mounting panel (1) under dynamic action, (15) the waist shape boss of end, with main shaft (6), (15) the cantilever cam (5) that matches of end waist shape boss, (16), be arranged on the mounting panel (1) can be around step axle (4), (8), (14), (17) pressing plate that freely rotates (3), (9), (13), (18), be arranged on the travel switch (2) on the mounting panel (1), (10), (12), (20), with cantilever cam (5), (16) hinged connecting rod (11) and upper limit thereof are dodged groove.
