I have TWO RH 072 Command switches (6-81952), ONE LH 072 Command switch (6-81953) and ONE LH 072 remote switche (6-12048). All swiches have been cleaned and tested to work- the LH command switch only switches in one direction, but not the other. It could be a faulty remote switch, as the non derailing feature still works. The command switches are about a month old- looking to get $80/ea on the RH command switches, $70/ea on the regular remote switch, and $50 for the LH command switch. Buyer to pay actual shipping. Thanks for looking.
