Abstract

The purpose of the invention is to realize the miniaturization of the handling portion of the press button and the operation improvement of the two-way press-button switcher, in which the component number and the assembling work are reduced to decrease the production cost. In the two-way press button on / off implement provided with a two-way press button, the on / off mechanism portion and the interlocking mechanism, a recessed portion is disposed on the bottom face of the housing of the on / off implement. The structure of the base station is constructed by disposing the base station through integrating the internal bottom portion of the housing in the upper recessed portion together with the housing so as to fix the movable body, which has the movable contact and is located opposite to the fixing contact of the base station, and the press button of the movable body on the pressing member having the protruding operation hole.

Description

technical field [0001] The invention relates to a forward and reverse pushbutton switch with an interlocking device used in the forward and reverse running control of cranes, winches and the like. Background technique [0002] Existing positive and negative button switches, such as Figure 11-1 As shown in 4, 1 is the shell, 2 is the cover, 3 is the switch element with an interlock mechanism, which is fixed in the shell 1, 4 and 4 are buttons, which are arranged on the switch element 3, and the button 4, 4 protrude from the housing 1, and the positive and negative switching action of the contact of the switch element 3 is performed by pressing the buttons 4, 4. In this structure, after assembling the interlock mechanism part and the switch contact mechanism part in the element case 5 and the element cover 6 of the switch element 3, they are fixed in the positive and negative push button switch case 1 and the cover 2. The structure of the switch element 3 therefore requires ...
