Contacted with the first self-reset oscillation part 53 due to, due to the first self-reset oscillation part 53 be in the first swing component only put position, first
The first crossbar and 52 block of signal lever of self-reset oscillation part 53 cooperate, and cam 2 rotates at this time, as shown in figure 9, the first Self-resetting
Swing component 53 presses signal lever 52 under the effect of cam 2, and signal lever 52 presses button triggering separating brake travel switch and issues separating brake letter
Number.
When cam 2 is mobile to ground connection open position from contact of earth position, cam 2 is rotated counterclockwise, cam 2 first with
The contact of first self-reset oscillation part 53, the first self-reset oscillation part 53 only put position to far from the first swing component under the effect of cam 2
Direction swing, until cam 2 and the first self-reset oscillation part 53 disengaging, effect of the first self-reset oscillation part 53 in its torsional spring
Lower reset, as shown in Figure 10, cam 2 continue to rotate counterclockwise and contact with the second self-reset oscillation part 54, the second Self-resetting pendulum
Moving part 54 is in the second swing component and only puts position, and cam 2 rotates at this time, and as shown in figure 11, the second self-reset oscillation part 54 is in cam 2
Signal lever 52 is pressed under effect, signal lever 52 presses button triggering separating brake travel switch and issues sub-gate signal.
In the present embodiment, the first self-reset oscillation part 53 is in the first swing component and stops the first self-reset oscillation that pendulum position refers to
Position of the part 53 relative to signal lever 52, the second self-reset oscillation part 54 are in the second swing component and stop the second runback that pendulum position refers to
Position position of the swing component 54 relative to signal lever 52, the length of the first, second self-reset oscillation part 54, position are according to actual peace
Holding position is configured.
The specific embodiment 2 of tri-station isolating switch of the invention, the structure of the tri-station isolating switch in the present embodiment
Difference with the structure of above-mentioned tri-station isolating switch is only that：As shown in Figure 12 and Figure 13, the signal lever 252 in the present embodiment
It is equipped with two-way only goods of furniture for display rather than for use 253, has first to stop pendulum position and second on the two-way oscillating stroke for stopping goods of furniture for display rather than for use 253 and only puts position, cam
22 by isolation closing position move to isolation open position when by first only pendulum position it is two-way only goods of furniture for display rather than for use 253 press signal
Bar 252 triggers separating brake travel switch, by stopping in first when cam 22 moves to ground connection open position by contact of earth position
The two-way only goods of furniture for display rather than for use 253 of pendulum position presses signal lever 252 and triggers separating brake travel switch 25.Two-way only goods of furniture for display rather than for use 253 and above-mentioned clamping plate type
The difference of swing component is only that, is set on two-way only goods of furniture for display rather than for use 253 there are two crossbeam 250, two crossbeams 250 stop goods of furniture for display rather than for use two-way respectively
In first, only only pendulum position is cooperated with signal lever block for pendulum position, second.
The specific embodiment of travel switch of the invention, the specific embodiment of travel switch and above-mentioned tri-station isolating switch
The structure of separating brake travel switch described in 1 or 2 is identical, repeats no more.
It is above-mentioned double in travel switch of the invention and the other embodiments using the tri-station isolating switch of the trip switch
