Resting across raised switches, bolt finally secured (7)
I believe the answer is:
astride
'resting across' is the definition.
I can't tell whether this defines the answer.
'raised switches bolt finally secured' is the wordplay.
'switches' is an anagram indicator (I've seen 'switch' mean this).
'finally' says to take the final letters.
'secured' indicates putting letters inside.
The final letter of 'bolt' is 't'.
'raised' is an anagram of 'asride'.
'asride' enclosing 't' is 'ASTRIDE'.
Can you help me to learn more?
(Other definitions for astride that I've seen before include "Not side saddle" , "With legs apart, emitting tirades" , "With legs on each side" , "Straddling (horse)" , "With one leg on either side, as sitting on horse" .)
