Problems solved by technology

There are many related technologies of this type of switch. For example, CN2123816Y discloses a non-contact travel switch, CN2141122Y discloses a kind of explosion-proof proximity travel switch, and CN2119031Y discloses a magnetic proximity switch. The contact connection and disconnection structure belongs to the direct push type, the reliability is average, the shock resistance is not strong, and the external magnetic body is made larger
For another example, CN1218587A discloses a kind of magnetic proximity switch system, and CN2289293Y discloses a kind of permanent magnet proximity switch, and its practicability is relatively poor

Embodiment Construction

[0038] Figure 1, figure 2 As shown, the first embodiment of the present invention has a switch body installed on a stationary object, and an approach block 7 installed on an external moving object A made of permanent magnetic material or magnetically permeable material. The switch body has a shell 1 made of non-magnetic material, a switch pair (or contact group) consisting of at least one static contact and at least one corresponding movable contact, an insulating bracket 2, a support shaft 16, and a main swing arm. 3. The permanent magnet 4 and counterweight 15 installed on the main swing arm, the auxiliary swing arm 9 and the shaft body connected with the active body. The static contact and its corresponding moving contact constitute a switch pair or contact group as used in existing travel switches, push button switches, micro switches or relays, and can be designed to include several pairs of normally open and / or normally closed contact type. The moving contact and the s...

Abstract

This invention relates to swing arm magnetic switch with switch body and close block, wherein, The switch body has shell, switch axle composed of static and dynamic probes; the shell is located with isolation rack fixed on the supportive axle and static probes; the supportive axle is fixed with reverse main swing arm at an angle around; the main swing arm is fixed with one permanent iron to make the main arm rotate for an angle through the above close block; the dynamic probe is directly fixed on the main swing arm to keep electrical connection to realize dynamic and static probes.

Description

technical field [0001] The invention relates to an electrical switch for position detection and control, in particular to a swing arm type magnetic proximity switch. Background technique [0002] In the prior art, there are many types of electrical switches used for position detection and control. The most traditional ones are various travel switches and micro switches. The disadvantage is that the object to be detected needs to contact and collide with the switch to make the switch actuate. There are three types of switches that do not require contact and collision: the first type is an electronic proximity switch made of active components; the second type is a magnetic switch made of a dry reed switch and a wet reed switch; An electrical contact similar to a switch and a relay, a non-contact switch that is turned on or off by a permanent magnet. Compared with various traditional travel switches and micro switches, this type of switch overcomes the ...
