5�� Institution and characteristics:
The F9 series auxiliary switch is composed of multiple sections, and its internal structure is shown in Figure 1. There are labels on both sides above each section indicating the number of this contact. The diagonal lines in the same section form a pair of normally open (or normally closed) circuits, and the determination of normally open (or normally closed) is displayed by the indicator on the operating shaft. The indicator points to a set of contact limits, indicating that this set is a reliable pair of normally closed contacts (circuits), and the rest are a pair of normally open contacts.

The contact between the dynamic and static contacts of this series of auxiliary switches is made by a circular sliding crimping method. The pressure between the hoes is generated by a separately set compression spring, which is non-conductive and far away from the heating part. The movable hinge joint of the static contact is connected by bare copper wire welding, making the current performance more reliable
The delayed quick action mechanism is flexible in operation, precise in timing, and switches quickly. The quick action mechanism only starts to drive the moving contact to rotate quickly after the active arm rotates to 65 ° -75 ° until the end point, and can reliably stay at the end position. Therefore, it meets the requirements of delay and quick action.

[auxiliary switch]ZFK6-8I/L Vacuum auxiliary switch

2026-6-16 20:41:38

ZFK6-8I/L vacuum auxiliary switch is suitable for controlling the closing, opening, interlocking, signal circuit of high-voltage switch operating mechanism and various high-voltage switchgear. It can also be used as a conversion or combination switch, as a substitute for mechanical or auxiliary switches.

1. Product Overview:
At present, the F series auxiliary switches used in domestic isolation switches and other electrical appliances adopt mechanical friction contact type, which generally has problems such as unreliable contact, poor environmental adaptability, low protection level, and short service life. To solve these problems, our factory has developed a novel ZFK6 series vacuum auxiliary switch by replacing mechanical contacts with vacuum reed switches. Its high on/off reliability, 100000 contact life, maintenance free performance, and good compatibility make it the preferred product to replace F-series auxiliary switches. It is widely used in relay switching circuits and signal acquisition circuits, and is suitable for protection circuits, electromagnetic lock circuits, isolation switch auxiliary circuits, and circuit breaker secondary control intermediate circuits.

2. Structure and performance characteristics:
The ZFK6 series vacuum assisted switch adopts the same appearance and size to achieve full compatibility.
The core components of the ZFK6 series switch are sealed as a whole to enhance reliability, and the rotor of its moving part is installed with permanent magnetic steel. Placed on the fixed plate, it does not generate friction with the fixed plate, so the rotation of the shaft is light and flexible, and there is no mechanical jamming.
The head of the switch adopts a quick action mechanism. When the shaft rotates to 75 °, under the action of the energy storage spring, the movable block drives the rotor to move quickly and reliably stay at the end position. The wiring terminal adopts composite slot combination screws, and the pressure washer automatically rises and falls with the tightening and loosening of the screws, making wiring convenient.
Compared with the commonly used F-series mechanical contact auxiliary switches in China, the ZFK6 series vacuum auxiliary switch has a series of advantages:
Adaptable
Mechanical contact switches can quickly experience poor contact due to corner corrosion in corrosive environments. The contacts of ZFK6 series switches are sealed in vacuum tubes, ensuring good on/off performance even in dusty, humid, and corrosive environments. In addition, considering the need for users to replace old switches and adapt to various installation scenarios, the ZFK6 series vacuum switches have taken into account different installation methods, rotation angles, and center height requirements. Except for the main and auxiliary nodding of the circuit breaker, it can replace all auxiliary switches of the F series.
Long lifespan, anti-interference
The lifespan of the vacuum tube of the ZFK6 series switch is 2 × 104 analysis times, which is much higher than the 20000 times of mechanical contacts; The permanent magnetic steel that controls the on/off of the switch is made of rare earth magnetic materials, which have strong magnetism and never demagnetize. The structure of the switch itself can effectively resist various magnetic and electric field interferences.
High strength, no need for maintenance
The components of the F series switch are relatively scattered and require frequent maintenance due to their inherent unreliability. The ZFK6 series switch seals the core components vacuum and connecting copper sheets with epoxy resin in a fixed plate, which has high mechanical strength and fundamentally eliminates the possibility of unreliable contact, saving the trouble of frequent maintenance.
High reliability of electrical contact
In the past, the on/off of F series switch contacts was achieved through mechanical friction contact. The arc produced causes the contact surface to burn black, seriously affecting the contact reliability. However, the contacts of ZFK6 series switches work in vacuum or inert gas media, and do not generate arcs under specified currents, ensuring good electrical contact reliability.

[auxiliary switch]ZKF series auxiliary switch

2026-6-16 20:36:44

The ZKF series auxiliary switch adopts the same appearance and size as the F series Tianguan to achieve full compatibility. The external dimensions of ZKF6 switch and F6 new auxiliary switch are completely consistent, with small size and higher reliability.
The core components of the ZKF series switches are sealed as a whole to enhance reliability. The moving part - the rotor - is suspended in the fixed disk by the action of a magnetic field, and there is basically no friction with the fixed disk. Therefore, the rotation of the shaft is light and flexible, and there is no situation of large mechanical jamming.
The head of the switch adopts a quick action mechanism. When the shaft rotates to 75 degrees, under the action of the energy storage spring, the movable block drives the rotor to move quickly and reliably stay at the end position. The wiring terminal adopts composite slot combination screws, and the pressure washer automatically rises and falls with the tightening and loosening of the screws, making wiring convenient.

The ZKF series auxiliary switch has a series of advantages compared to the F series mechanical contact auxiliary switch commonly used in China recently:
1. High reliability of electrical contact
The on-off of F-series switch contacts is achieved through mechanical friction contact, and the generated arc causes the contact surface to burn black, seriously affecting the contact reliability. The contacts of the ZKF series switches work in vacuum or inert gas, and basically do not generate arcs, ensuring good electrical contact reliability.
2. High mechanical strength, no need for maintenance
The components of mechanical switches are relatively scattered and require frequent maintenance due to their inherent unreliability. The ZKF series switches seal the core components of the vacuum tube and the connecting copper sheet with resin in a silent disc, forming a whole layer. Its mechanical emphasis is high, fundamentally eliminating the possibility of unreliable contact, thus saving the trouble of frequent maintenance.
3. Long lifespan and strong anti-interference ability
The lifespan of the vacuum tube of the ZKF series switch is 100000 times of breaking capacity, far higher than the thousands of times of mechanical contacts. The permanent magnetic steel that controls the on-off of the switch is made of the best magnetic material - neodymium iron boron, which has strong magnetism and never demagnetizes. The structure of the switch itself can effectively resist the interference of various magnetic fields and electric fields.
4. Strong adaptability
The ZKF series switches are not limited by dusty environments due to their sealing properties; Good on/off performance can be ensured even in humid and corrosive environments with a wide temperature range. On the contrary, switches with mechanical contacts quickly experience poor contact due to contact corrosion in corrosive environments.
Considering the need for users to replace old switches and adapt to various installation scenarios, the ZKF series switches have taken into account different installation methods, rotation angles, and center height requirements. It can almost replace all auxiliary switches of the F series.
