Abstract
The utility model relates to a reversing switch, which belongs to the technical field of electric switches, and is composed of a frame 1, a braking rod 8, a supporting ratchet wheel 6 for a movable contact, a braking ratchet wheel 7, a check movable sheet, etc. The utility model has the advantages that when the reversing switch is used on a daylight lamp, the service life of the lamp pipe can be extended. Meanwhile, the reverse rotation and the forward rotating of an AC motor, the operating mechanism of a stop button, and an operating mechanism for phase changing and adjusting on an AC and DC two-purpose series-excitated type motor can be simplified by adopting the reversing switch.
Description
The utility model belongs to the appliance switch field.
At present, because the aging difference at fluorescent tube two ends is excessive, and cause fluorescent lamp to shorten greatly useful life.
The utility model has solved fluorescent lamp one end and has connected with power firestreak for a long time, thereby make the filament too fast problem that wears out, adopt this switch can simplify the alternating current motor counter-rotating, just change simultaneously, the stop button operating mechanism is simplified the commutation of the dual-purpose series excitation type motor of AC and DC and is turned operating mechanism.
The utility model theory structure is as follows:
On framework 1, fix a slidably brake bar 8, at brake bar 8 one ends one action button 11 and brake bar back-moving spring 12 are arranged, one fixing axle 2 is arranged on framework 1, one brake ratchet 7 is arranged in the middle of axle 2, respectively there is a movable contact to support ratchet 6 in brake ratchet 7 both sides, two movable contacts support on the ratchet metal movable contact 4 is arranged all, movable contact 4 can be communicated with the metal clips on the load fixed contact 5 or disconnect, movable contact 4 rolls with power supply contact 3 and is communicated with simultaneously, and is middle by check operation strip back-moving spring 10 is arranged at brake bar 8.
When promoting brake bar 8, check operation strip 10 promotes brake ratchet 7, but because brake ratchet 7 is that arcuate movement check operation strip 10 can not be pushed ratchet to 90 jiaos, at this moment the fixedly card that another braking ratchet that turns later just in time is braked bar 8 back blocks pushes 90 jiaos to, movable contact is communicated with the load side fixed contact or disconnects, its operating state is: just → stop → anti-→ stop.
The utility model advantage is: this switch patrols ring through one on switch switch, the output line of ballast and the zero line of power line just transposing once, it is on average aging and reach the purpose that fluorescent tube increases the service life to make it the filament at fluorescent tube two ends.
Fig. 1 is the phase-change switch front view.
Fig. 2 is the phase-change switch rearview.
Wherein: the 1st, framework, the 2nd, axle, the 3rd, power supply contact, the 4th, movable contact, the 5th, the load fixed contact, the 6th, movable contact is supported ratchet, the 7th, brake ratchet, the 8th, brake bar, the 9th, check operation strip, the 10th, check operation strip back-moving spring, the 11st, action button, the 12nd, brake bar back-moving spring, the 13rd, crossbinding winding thread.
Claims (1)
1, a kind of reversing switch, by crossbinding winding thread 13, action button 11 is formed, and it is characterized in that:
On framework 1, fix a slidably brake bar 8, at brake bar 8 one ends one action button 11 and brake bar back-moving spring 12 are arranged, one fixing axle 2 is arranged on framework 1, one brake ratchet 7 is arranged in the middle of axle 2, respectively there is a movable contact to support ratchet 6 in brake ratchet 7 both sides, two movable contacts support on the ratchet metal movable contact 4 is arranged all, movable contact 4 can be communicated with the metal clips on the load fixed contact 5 or disconnect, movable contact 4 rolls with power supply contact 3 and is communicated with simultaneously, and is middle by check operation strip back-moving spring 10 is arranged at brake bar 8.
