## Microswitches
Used for limit switches.
Used for limit switches. Currently only the button type is supported as the lever and roller types are less accurate.
The switch is drawn with the button at the nominal operation point. This can be plus or minus `microswitch_op_tol(type)`.
When the button is released it comes out by a maximum of `microswitch_fp_max(type)` from the nominal operating point.
