Embodiment Construction

[0038] see figure 1 , figure 2 and image 3 As shown, the improved structure of the switch device of the present invention selects a limit or travel switch device as an illustrative embodiment. The switch device shows a structure in which three contact bases 10 combined side by side are fastened to a contact frame 20 ; the contact frame 20 cooperates with screws 30 to fix a fixed plate group or fixed plate 40 . The fixing plate 40 allows the actuating rod 50 to extend into the contact frame 20 to touch the contact seat 10, thereby forming a function similar to that of a conventional limit switch.

[0039] In the preferred embodiment adopted, the contact base 10 has an insulating shell defining an axis X; the contact base 10 has a first end wall 11, a second end wall 12, two side walls 13, an upper portion 14 and a bottom 15 , and jointly define a chamber 16 for disposing the wiring assembly 55 . The first end wall 11 and / or the second end wall 12 of the contact base 10 pr...

Abstract

The invention discloses an improved structure of a switch device, and provides the improved structure that is simple and easy to mount and dismount, etc. The switch device comprises at least one contact stand. The contact stand is provided with a first end wall, a second end wall, two sidewalls, an upper portion and a bottom portion, which all together define a chamber to configure a wiring assembly. The first end wall and the second end wall of the contact stand are each provided, in a protruding manner, with a combination part and an oblique groove that faces the combination part and is associated with the combination part. A contact support assembled with a fixed plate is equipped with lock joint portions, and can be buckled to the combination parts in a detachable manner. A worker is allowed to operate a tool to directly detach the lock joint portions from the combination parts through the oblique grooves so as to quickly install and detach the contact stand and the contact support. The problems in the prior art that an assembly is complicated, is difficult and time-consuming to install and detach or the like are overcome.

Description

technical field [0001] The invention relates to an improved structure of a switch device; in particular, it refers to a switch device structure in which a contact seat of a limit switch device is provided with a combination part and an oblique groove, allowing personnel to easily assemble and disassemble the combined contact frame. Background technique [0002] The switching device used in motor, electronic, and automatic control systems to allow the operator to operate the machine, provide instructions, or power on and off is already a prior art. For example, the limit switch or travel switch used to control the movement stroke of mechanical equipment is usually installed in a pre-arranged position; when the moving parts on the machine hit the contact of the limit switch, the limit switch performs circuit switching, Realize the functions of controlling the travel of mechanical equipment and terminal limit protection. [0003] Existing limit switch devices usually include a...
