These crusher instances are aviable for 1 side and 2 sides (opposite).
You can do the following:
Use a Reset Timer for auto-reset after crushing.
Use a Solved-Relay that brings the crusher to "de-crushes" state (even if moving).
Use single relays just to crush or uncrush without any automatic reset.
Use the Status value - set a name of a math_counter and the crusher will add 1 if crushing and subtract 1 if uncrushing. (For multiple crushers).

Just don't forget to kill/deactivate the not used features with a logic_auto at mapspawn.

Use this well-thought-out crusher system to create crushers in all variants easily.
