You Should Know About Cam Switch ? By changing the angles at which a handle and shaft are turned, it is a switch that transmits electrical energy.
By rotating the switch through different positions, a cam switch can be used to carry out make and break operations sequentially.It is possible to control different circuit operations by rotating the cam that closes and releases the contacts.
Different Cam Switches
There are various cam switch varieties. As an illustration, TME provides a broad selection of cam switches, such as isolator switches, multistep switches, changeover switches, ammeter selector switches, gang switches, and many more. Visit TME Electronic Components to find a variety of cam switches if you’re looking to buy your first one:
Several-Step Switches
Multi-step switches enable multiple circuits to share a single power source.
With two- and three-phase power sources, respectively, single-pole, double-pole, and three-pole switches are frequently used.The tapchanging switches for stabilisers and transformers can benefit from multistep switches.
Switches for Voltmeters
With the aid of isolator switches, which are ON/OFF switches, you can completely turn off the power to a particular area of operation.
Uses: For specialised applications in the main, controller, and instrumentation circuits, on-off, motor, and other switches.
Switches for ammeter selection
There are typically three positions on the ammeter selector switch.
A three-phase system requires ammeters in each line to monitor current.
Switches for motor controls
These switches are frequently used to control two-speed forward-reverse, star-delta, and forwardreverse motors. These switches are perfect for use with contactors due to the overload and power failure tripping features built into them.
Activation Switches
The vast majority of switches are “spring return” types, which latch the circuit with NO contact and facilitate the activation of the tripping mechanism.
Control switches provide a special substitute for numerous “Push Button Stations” when one switch controls instead of many push buttons, and there are a number of settings available on the control switch to select the ideal setup.
The advantages of using a cam switch are as follows:
- Simple to use
- inexpensive item
- Little in size
- Application of AC and DC
- Maintenance-free
- It has a high level of IP security.
- Simple to install
Negative aspects of a Cam Switch
The cam switch can only be operated manually; not remotely. It can’t switch to currents that are very high. It needs physical rotating power to be activated. There is no protection against thermal and magnetic currents in a cam switch.
