Abstract: PURPOSE: To lessen the number of parts and simplify the structure by making no need of a movable member to install a movable contact and also making no need of a driving mechanism to pressure contact the movable contact with a fixed contact or turn back the movable contact from the fixed contact. CONSTITUTION: A circular conductive path 4 having a center opened part 40 is formed on the surface of a stand 3 made of an insulator and an input lead 6 penetrating the stand 3 and projected out downward is installed in the surrounding of the conductive path 4. Moreover, an output lead 5 penetrating the stand 3 and projected out downward in the same way is installed in the center opened part 40. A coil spring 2, which becomes a movable contact, is fixed in the tip part of the lead 5 and an insulating push button 1 having a spring stopping axis 10 in the lower part is installed in the upper end part of the spring. In this structure, sealing is done while all of the upper face part of the stand 31 being surrounded with a case 7 and only the button 1 being exposed.  Next, to form a contact, the button 1 is pushed down to contract the coil spring 2 and to bring the spiral part of the contracted spring 2 itself into contact with the conductive path 4 and thus the leads 5, 6 are set in electrically communicated state.

Inventor: HIGUCHI YUJI
IPC: H03F1/52
Filed: 1985-09-04
Abstract: PURPOSE:To prevent the increase in the collector loss of a klystron by interrupting a high voltage power supply when the level of a high frequency input signal of the klystron amplifier is lower than the normal range. CONSTITUTION:A level of a signal extracted by a directional coupler 5 as a part of an input signal of a klystron amplifier 1 has a correlation with an output signal of the klystron amplifier 1.
