Switch allows "Write" converter function only

[peperoni60]

Describe the bug
If you add a new switch in the device manager, and you want to add a converter function, only "Write" is possible whereas "Read" should be the only possibility. In consequence, the alias doesn't work. You can change that, however, via objects by modifying the datapoint, check "use converter function", and adding the converter function to "read". Then the alias works as expected (clicking "On" on the switch switches the datapoint to "On", clicking "Off" switches to "Off".

To Reproduce
Steps to reproduce the behavior:

1. Go to "Devices"
2. Add a Switch to the devices list
3. Use the physical switch
4. See nothing happens

Expected behavior
When clicking the Off and On buttons on the physical switch this should be reflected in the alias.
