Novel structure of smll selective switch

Abstract

The invention discloses a novel structure of a small selective switch with a mounting hole of phi 19mm. The switch comprises a knob handle, a clamp spring and a metal shell connected with the knob handle, a pressing plate connected with the metal shell, clamping seats, a clamping seat spring placed at the head parts of the two clamping seats, collision beads mounted on the clamping seats, a rotating plate, a static contact pin A, a static contact pin B and a switch seat for mounting the static contact pin A (the static contact pin B). The invention has the following characteristics: 1, the diameter of the mounting hole is phi 19mm, and the product size is small; 2, the shell and the knob handle are made of metal materials, so that the damage resistance is good; 3, five gears are provided,and on-off of four pairs (eight groups) of switches can be controlled at most; and 4, the switch rated value reaches 2A / 250VAC.

Description

technical field [0001] The invention relates to the technical field of buttons, and more specifically relates to a novel structure of a small selector switch. Background technique [0002] 1. At present, the gear positions of domestic and foreign selector switches are usually controlled by internal cams. Due to structural limitations, there are at most 3 gear positions to control 3 groups of on-off. [0003] 2. At present, domestic and foreign products that can control circuits and have multi-level switching (such as digital coding band switches) have a small rated current and cannot meet the control of large current loads. For example: DPP series digital coding of foreign TOSOKU Dongtest Company Band switch, its rated capacity is: 0.5A / 5VAC, 0.05A / 48VAC. [0004] 3. At present, some domestic and foreign selector switches with relatively large rated current have a relatively large overall volume, for example: XB2B series selector switches of foreign Schneider companies. ...

[0005] 4. Based on the above content, if you want to provide a 5-position high-current metal anti-damage selection switch that controls the on-off of 4 pairs (8 groups) of switches on the φ19mm installation panel, and at the same time ensure that its overall size is small and exquisite, it is popular both at home and abroad. There is no such product in the market
