The module seems to use paramiko_ssh 
<https://github.com/CaptTofu/comware_5_2/blob/master/comware_5_2.py#L93> to 
connect to the remote host.
Try changing the inventory entry as below since the module is expected to 
run on the control node.

[switch1]
192.168.xx.xx ansible_connection=local

OR

[switch1]
localhost

Also, this seems to be a very old module and not using the Ansible 
persistent connection framework.
You can add Ansible cliconf and terminal plugins for the network os to make 
it work with connection=network_cli 
<https://github.com/ansible/community/blob/master/group-network/network_dev_network_cli.rst>
After adding the required plugins you use cli_command  
<https://docs.ansible.com/ansible/latest/modules/cli_command_module.html>and 
cli_config 
<https://docs.ansible.com/ansible/latest/modules/cli_config_module.html> 
modules 
to manage the remote host.
