I want to know if I can bypass the switch to check the submersed pump?

I have no water,what can I do to check well pump. It is a submeresed pump

You can jumper past the switch but just to check it.

The simple answer is yes. However, you should be able to simply open a faucet and let the pressure drop until the switch clicks as the points close. You can then use a voltmeter to make sure you are getting power to the pump.
