Since the front is replaced by a varactor diode, there is room for the right space, so that the right mouse button can be switched back and forth. This switch seems to be dedicated to the frequency meter.
The left mouse clicks the "single tube" and the right mouse button switches the frequency meter. A perfect match!

Wonderful design that simplifies the circuit, switching
This frequency meter uses only one power switch
The frequency segment switch is implemented on the probe (this saves space inside the mouse)
