Description
Technical field
The utility model relates to travel switch technical field, is specifically related to a kind of push type travel switch of adverse environment resistant.
Background technology
Travel switch is also known as position switch or limit switch; its effect changes mechanical displacement control signal into signal of telecommunication on-off function in circuit; device systems running status is changed; namely the power produced by mechanical action or moment pressing travel switch button certain displacement; drive the break-make of push type travel switch inner contact; control being switched on or switched off one or more signal of telecommunication with this, thus make the safeguard protection etc. of control signal conversion or realizing circuit (or control signal).Dissimilar pressing travel switch is widely used in the automatic control system of every profession and trade or the controlling functions modular converter of electromechanical assemblies.
Current push type travel switch generally adopts cantilever beam right as the contact of contact, vibrate (as 10 ~ 3000Hz in HI high impact (as half-sine wave 100g) or height, under adverse circumstances 30g), easily occur during connection that trembling of contact is disconnected, and easily occurring that trembling of contact is closed when disconnecting, both of these case all easily makes control circuit misoperation.Under HI high impact or the high adverse circumstances vibrated; as push type travel switch driven to realize being switched on or switched off (as provided ignition signal or safeguard protection signal by the action of push switch) of one or more signal of telecommunication by different mechanical displacement; when adopting current existing traditional push type travel switch to realize; for ensureing under the mal-condition of HI high impact, high vibration; push type travel switch can reliably be switched on or switched off signal and not occur misoperation, usually can adopt following two schemes:
