A cam switch is a device,which is intended for switching electrical circuits. The principle of the device is based on changing the clock frequency. Most often switches are found in transformers. They are also actively used in measuring instruments. In order to learn more about the switches, it is necessary to consider the circuit of the conventional modification.
The circuit of the switch contains contactsmobile type and switch. Directly the handle is fixed on the trigger. To change the position of the contacts of the device tetrodes are used. The regulator is installed together with the modulator. Filters are used to stabilize the frequency reduction.
The two-pin cam switch is idealsuitable for pulse transformers. In this case, the regulator is used with an adapter. The output voltage on the trigger is 3 V. Insulators are used with a protective winding. The current overload indicator is no more than 5 A. On average, the sensitivity of the modulator does not exceed 10 mV. The conductance of the current depends on the power of the modulator. For voltmeters, these devices are not suitable.
Switch (cam, batch) is producedfor measuring instruments. In this case, the modulator is used with an amplifier. On average, the current conductivity is 12 microns. Filters for models are installed both open and closed. Transceivers in all devices are used without an overlay.
Direct contacts are installed in the rearparts of the body. Regulators for models are designed for two or three phases. As a rule, triggers are used with the switch. The current overload rating is 12 A. For pulse transformers, devices of this type are not suitable. How to connect a packet type switch? This can be done through a contact adapter.
Switches for transformers canmade with a trigger. In this case, the modulators are used with a movable plate. Many models have a tetrode. It is installed together with insulators. Throughput filters are used to increase the switching speed.
In devices with triggers, the conduction parametercurrent is not less than 6 microns. It is also important to note that the sensitivity of the modulators depends on the threshold voltage at the output contacts. If we consider modifications of 15 V, then the above parameter does not exceed 40 mV.
Switches of this type are compact andoften produced in three phases. Many models use an operative-type modulator. Contacts in the device are located in the back of the case. Many models use an expander. This element plays the role of stabilizer.
To increase the conductivity of the current,tetrodes. These parts work from the trigger. They can connect through the plate or insulators. Speaking about the indicators, it is important to note that the output threshold voltage of the switches is on average 20 V. The conductivity parameter of the current with operational triggers does not exceed 14 microns. Filters in many devices are used without conductors.
Cam switch for ammetersis highly sensitive. Many modifications are designed for three phases. Triggers in devices are assigned a two-transitive type. Expanders in this case play the role of stabilizer. Many devices for ammeters use operational modulators. These elements are able to work only with the kenotrons. To connect them, low-frequency adapters are used. The parameter of the output voltage on the trigger is about 12 V. It is also important to note that the current conductivity, as a rule, does not exceed 5 microns.
Cam switch for double-windingengines is pretty much in demand. On the average, the output voltage parameter of the models is 3 V. Modulators in devices are of the pulse type or of the operational type. Switched analogs are very rare.
To stabilize the circuit switching processfilters are used. Many devices have protective tetrodes. These elements are installed through the conductor. The output frequency parameter for the models is 40 Hz. The sensitivity index fluctuates around 3 mV. However, if we consider modifications with two-bit flip-flops, then the above-mentioned parameter is 5 mV.
A switch circuit of this type impliesuse of the operational trigger. Modulators can be installed with an overlay. In this case, transceivers are used without filters. For impulse transformers, the models are ideal. The devices are produced in two and three phases. If we consider the first variant, then the expander is of the switched type. In this case, the current conductivity parameter is about 6 microns.
The output voltage of the switches varies inregion of 12 V. If we consider devices in three phases, then they use a dipole expander. A distinctive feature of such devices is hypersensitivity. A model of this type can also be used for step-down transformers.
Switches of this series are suitable only forstep-down transformers. Modulators in devices are of a switched type. Regulators are installed in three phases. Contacts at the models are located in the back of the case. Many modifications of this series are made without facing. Direct connection of the device occurs through the expander. It is also important to note that in the market are devices with dual-charge triggers. A distinctive feature of these devices is hypersensitivity. The threshold voltage of the modifications is 14 V.
On average, the current overload parameteris 3.5 A. In this case, the modulators are installed with insulators. Also there are modifications with three-bit triggers. They differ in the increased conductivity of the current. Suitable devices for this type of low-frequency transformers. The parameter of electricity consumption is low. How to connect the switch of this series? In fact, this can only be done through a contact adapter.
Cam switch 4G10 is suitable for bothlowering, and for impulse transformers. The current conductivity parameter of the models is 6 μ. In this case, the operating frequency is around 45 Hz. Most of the modifications of this series work on phase expanders. For such devices, modulators with transceivers are suitable.
Regulators are often installed without a tetrode.The sensitivity parameter does not exceed 10 mV. It is also important to note that there are modifications on resonant expanders. Their distinguishing feature is the high current overload parameter.
The operating frequency of the models is about 55 Hz.Current conductivity of the models is 12 microns. The threshold voltage is 8 V. For power transformers this type of device is not suitable. It is worth a switch cam (price market) about 1500 rubles.
