I face difficulties when switching to other chords. Is there an easy way to learn switching?

There are many ways to learn to switch. The secret is to play it slow.

The simplest and best way would be to start a metronome and practice at a slow speed. Practising without a metronome may work, but it's not going to give you a good foundation for being a musician. 

Practising with a metronome will make the foundations strong for you to build on, so start at the speed of 50 to 60 and start playing the chord switching on every "whole note".

Remember, slow and steady wins the race, so it's essential to practice every day, even if it's for 5 mins - rather than playing 1 hour once a week! 

Hey Saurabh!
I will suggest you focus on the transition from one chord to another. Figure out yourself the least finger change/movement you need, to shape another chord.
Suppose you are holding 'C Major'[(5:3) (4:2) (2:1)] and you want to change it to 'A Minor'[(4:2) (3:2)(2:1)] then you just have to move your 3rd finger from C note(5:3) to A note(3:2). Find these out yourself, and it will be more comfortable. That's just one process. You can practice on the metronome. Also, it will help.

Yes. Of course.
First of all, learn the basic chord shapes in the nut position (open string position ). Then try to play a straightforward strumming pattern like DDDD on any chord. Begin slowly. Once you have mastered this four downstroke strumming pattern on a single chord, then try to switch to the next chord in the progression. But again go slow when you are starting with. The best way to probably get it right is by using a metronome. Set the metronome on 60bpm and 4/4 time and then try to play these chord changes on these counts. And then you can gradually increase the tempo and make some more interesting strumming patterns of your own. But the most important thing is that you have to be patient in this entire process and keep practising. Eventually, you will be able to play beautiful chord changes and make good music.

The easiest method is a practice only one particular chord that you face difficulty changing. Let's say it's F major. What you do is play F major then immediately leave it. Please put all your fingers on F major n again immediately take them off. Do this to get hold of one chord once you are comfortable with it. Check from what chord to what chord is a problem. Then practice both the chords in a similar fashion. Moreover, try to shift between those two chords only. I.e. F major and G major.

• Practice finger independence exercises and try to find anchor points between chords.
• Another exercise you can try is setting a metronome to 60 BPM and then switching chords on every 1st beat, and gradually make it faster, while consciously trying to move all fingers together instead of one at a time. Once you reach 200-240 BPM your chord switching should be good enough to play most songs!
