Embodiment Construction

[0014] The purpose of the present invention is achieved like this: as ( figure 1 ), the left and right terminals (35) and right terminals (36) are inlaid on the left and right sides of the auxiliary switch box 2 (51), which are used for connecting wires. The normal state of this auxiliary switch is the normally open state. The movable contact (38) makes the left binding post (35) and the right binding post (36) be in a disconnected state under the positioning of the upper spring (33) and the lower spring (34). Under the action of pressure, the auxiliary switch shaft (32) will drive the moving contact (38) to connect the left terminal (35) and the right terminal (36) after moving upwards for a certain stroke, so that it is in a conduction state. The switch shaft (32) has a certain overtravel under the action of the lower spring (34). Make moving contact (38) have certain contact pressure. Eliminate the pressure of the auxiliary switch shaft (32), and the movable contact (38)...

Abstract

Disclosed is a switch which is capable of controlling a circuit and an air line. A master switch has three positions and a multi-layer structure. Through the rotation of a switch knob (4), an auxiliary switch of each layer of the three positions can be respectively controlled and external force can be eliminated and then an initial position can be automatically returned. Auxiliary switches of the three positions are installed on the outer portion of a master switch box and are respectively a left auxiliary switch (21), a middle auxiliary switch (22) and a right auxiliary switch (23). A left spring seat (5) and a right spring seat (8) are used for fixing the rotary range of a spring column (9) and the rotary range of a locating arm (10). A left spring (7) and a right spring (8) are used for playing a locating function to the locating arm (10). The switch knob (4) is rotated, a shaft center (3) and the locating arm (10) can be driven to synchronously rotate, auxiliary switch shafts (32) on the three positions are respectively compressed, and therefore switching on and switching off of the left auxiliary switch (21), the middle auxiliary switch (22) and the right auxiliary switch (23) are controlled.

Description

technical field [0001] The invention relates to a switch, in particular to a switch capable of controlling electric circuits and air pipelines. Background technique [0002] The existing switch has the following defects: 1. The existing switch cannot control the circuit and the gas circuit at the same time. 2. The existing switch needs other auxiliary devices to control the air pipeline. 3. Existing switches cannot control more electric and gas passages. 4. Existing switches do not have specific sub-switches. Contents of the invention [0003] The present invention overcomes above-mentioned shortcoming etc. It can realize integrated control of electricity and gas. The rotary switch toggle can respectively control the electric and gas sub-switches in three layers on the left, middle and right positions, so as to realize one-key control of multiple electric and gas passages. After removing the external force, it can automatically return to the initial state and the midd...
