	One of the feasibility issues of the CLIC two-beam scheme is the possibility of rapidly switching off the RF power production in individual Power Extraction and Transfer Structures (PETS) in case of breakdowns, either in the PETS or one of the main beam accelerating structures. The proposed solution is to use a variable external reflector connected to the PETS. When activated, this scheme allows us to manipulate gradually the RF power transfer to the accelerating structure and to reduce the RF power production in the PETS itself by a factor of 4. Recently the first operation of the Two Beam Test Stand (TBTS) PETS equipped with an on-off mechanism has been performed in CTF3. In this paper we will present the results of the PETS operation when powered by the drive beam up to high peak power levels (>100 MW) and compare them to expectations.
