Microswitches
Microswitches are used primarily as paper size sensors and cover interlocks. They
are in a normally open state, and close when actuated. Microswitches frequently
employ hooks or catches on the switch housing for retention in the bracket or
frame.
Thermistors
Thermistors have a known value of resistance whose value varies with
temperature. Used primarily in the Fuser for temperature sensing.
